Connecting remote control. Universal remote for television, how to set up? Typical faults and their elimination

An independent installation of a simple wireless lighting control system with a radio radiopult occurs easily and requires minimal knowledge of electrical engineering.

We will understand in the varieties, details and principles of connecting remote switches operating on the radio channel.

IN wireless system Two main instruments are used by radio control via radio:

The command device is a portable or stationary remote.
Executive Module - Power Block (Radiole, Radio) or RGB controller.

Remote lighting control: 1 - radio; 2 - ceiling lamp; 3 - radio camery; 4 - sconce; 5 - wall remote; 6 - the light / motion radio switch; 7 - Portable Remote

Varieties and opportunities for radio

Portable radio transmitters are similar to the television or in the form of a keychain. The latter can be in his pocket or hang in the hallway and turn off the lighting throughout the apartment.

Wall-mounted radio results are available in three versions:

Touch-button panel (keys) for overhead, similar to a regular switch. It is glued with a double-sided scotchpiech or fixed by self-drawing at any dry place - where it is convenient, without thinking about laying the wires.
Insertion board for compatible push-button sensor. "Tablet" is installed inside the hidden installation box or in the case of the backs switch.
Universal radio transmitter to upgrade the current lighting scheme. It is located in a deep mounting box and works from the standard switch.

In addition to external view Radiopulists differ in a radius of action (up to 100 m) and functionality. The simplest models are single-channel, including and disconnecting a single lamp, sometimes can manage radioimme. Multichannel consoles work with several illumination zones and are configured using individual scenarios for each power module.

You can control the source of light from different places by installing one radio round near the door, and the other has a bed headboard. The only limitation is metal surfaces, weakening range, so do not secure the device for the refrigerator. When placing command and executive devices in different rooms, a decrease in the radio signal power is taken into account when passing through the walls and overlaps, if necessary, repeaters are used.

How to choose an executive block

The relationship between devices of various modifications can be carried out by different protocols. The joint operation of the radio switch and the console is possible only when they are compatible, which depends on the manufacturer and product series.

Load

Selection of the power unit is performed depending on the nature of the load. The power of the device, indicated as the maximum, corresponds to the load from incandescent bulbs and halogen to 220 V. for light sources connected through the transformer, use a lower ratio:

0.7 - for low-voltage "halogen";
0.5 - for luminescent lamps.

It is more difficult to determine the real load from energy-saving lamps, by virtue of their large starting current. A simple method that does not exclude overload and sintering contacts is to make a three-time power supply. Guaranteed method of protection against trouble - the use of a special module designed to work with LED and energy saving lamps, or with the ability to connect an external power relay.

Accommodation

The permissible switching power of the blocks is associated with their dimensions. Radiol for loading in 200-300 W is freely fit in many lamps - in size it is not more match box. Modules designed for 3-5 kW are equipped with cooling radiators and are much larger in size, but have a flat layout and easily hide in space behind panels.

Separate series of devices are available in REG-enclosures for fixing on DIN rails with a possible connection. external antenna. For work in wet conditions, receiving blocks with increased protection (IP65) are intended.

In addition to the commands from the consoles, the power modules are capable of working from signals from lighting sensors and movements equipped with radio channel. Equipment manufacturers for remote control The light is offered and ready-made sets with typical solutionsSimplifying selection suitable devices. The most elementary option is stuck in the radioadapter socket, which does not require installation at all.

How to connect the power unit

Principle of connecting the executive module initial level It is easy to understand: a phase and zero of the external network are fed to the input of the device, and the load is connected to the output. Swinked spiral antenna wire They are placed without drips, straight do not wind around the case, and try to straighten the most and not damage the isolation.

Attention! Electrical work is performed after disconnecting the power supply, connecting the wires high quality and correctly.

Certain types of loads: LAMM drivers, pulse converters etc., capable of creating high-frequency interference that prevent the correct operation of the devices. Light bulbs can blink or not disconnected, the malfunction is eliminated by inclusion in the ballast circuit - an interference capacitor by 0.47 μF / 275 V.

Connecting actuators: 1 - lamp; 2 - ballast; 3 - power unit for one channel; 4 - single-infunction radioimmer

Council. To avoid radio communication problems, the devices are placed no closer than 50 cm from household appliances and then 100 cm each other.

Minor complexities of connection are associated with the lack of a single standard of the color marking of the wires, which is solved attentively studying the instructions.

Connection diagram of power blocks: 1 - DELUMO Radio; 2 - Double-channel Gira-mini radio ammumber; 3 - lamp; 4 - load of the 1st channel; 5 - Load 2nd Channel

You can upgrade the existing lighting and leave the standard switches by installing both the radio transmitter and the receiving device that the signal from the console will be supplied to the active wiring.

Connecting embedded blocks: 1 - lamps; 2 - wired switches; 3 - radio ROP-02; 4 - wireless RFSAI-61B relay; 5 - external switch

The remote control circuit of LED ribbons is calculated and collected similarly wired, the difference is only in the controller equipped with a radio module.

Schematic diagram: 1 - power supply; 2 - RGB controller; 3 - tricolor tape

To change the brightness of the luminescence of monochrome lED tapes Suitable small-sized lights: 1 - power supply; 2 - signal amplifier; 3 - dimmer single-channel; 4 - monochrome tape

After connecting the equipment, the radio utilities are "tied" to power blocks and create the desired scenarios of the work of lighting devices. In some models, modes are switched by jumpers, in addition to the program setting.

Truble the simplest optionConsisting only from the receiver and the transmitter, you can check the convenience of the smart home system and continue expanding the complex, gradually adding new household devices.

Remote lighting control is not a luxury, such systems are vital necessity and very comfortable in concert halls, in stadiums and other public audiences with large areas. Remote control eliminates long transitions to switches. Exist different principles Works of these systems:

infrared;
in the range of radio waves;
via channels mobile communications and the Internet.

Remote control

With the development of technologies, the equipment has become cheaper and more affordable for ordinary consumer. Therefore, more and more often the lighting system with remote control is acquired, collected and installed in apartments, individual houses. The process of connecting the remote control system is not complicated, but parts depend on many factors:

in which range the system is running;
what lamps are used - incandescent, economy daylight, halogen or LED;
distance to chandelier and place of its location.

All this determines how to connect a chandelier with a remote control, based on local conditions. To understand the actions algorithm, it is worth considering the easiest way to connect a chandelier with remote control in an apartment or a private house.

Connect chandelier to double switch

Fastening and connecting wires

The method of fastening the chandelier to the ceiling remains the same. Classic options include a hook or metal DIN rails, which are screwed into the ceiling and the chandelier housing is fixed on them. For each model, an instruction is attached how to do it.

Hook for mounting chandeliers on the ceiling

Metal strips for fastening chandeliers

Complexity when assembling a remote control system, the chandelier connections is to install the controller. The controller is one of the most important elements of the remote control system, it takes the signals sent from the remote control or stationary switch, and performs the switching signal for the installed lighting mode. Options may be very different:

the inclusion of individual groups of lamps on the chandelier;
adjustment of the brightness of the lighting;
the stationary remote is the function of finding a remote console - the corresponding button is pressed and a signal is fed, which includes a melody or tone sound on the remote remote control, which greatly facilitates its search.

Usually the controller has small dimensions and easily placed under a decorative chandelier cap, which closes the block of connecting wires on the ceiling.

Installing the controller in the chandelier housing

You can install the controller in the wall with a stationary switch or elsewhere, for this you have to stretch from it the wires to the chandelier and stationary control panel.

In the lighting apartments usually include a double or triple switch, the controller expands these capabilities.

Various models of controllers have differences in connection schemes. To each product attached electrical circuit, sometimes even the pictographic pattern, where the color of the wires and the connection site is specified. When assembling, it is recommended to adhere to these instructions. In most cases, on the controller, three contacts for connecting to the network - phase, zero and grounding, and 2-4 contacts to individual groups of lamps that are connected to the chandeliers are connected to the phase wires (usually brown).

Single-channel controller and remote control

All zero ends are connected by a twist into one contact, which is isolated by the cambrick, tape or special plastic caps. Grounding wires (yellow-green) are connected in the same way and fixed by the chandelier bolt provided for this. If there is no such fastening, it is allowed to insulate the contact and do not connect anywhere.

Multichannel controller and remote control for chandeliers

Installation of the controller and all electrical connections Made with a de-energous network in the premises of this building.

Connect to the controller and remote control

Such chandeliers have more multifunctional controllers, they control not only the inclusion of individual groups of LEDs, the intensity of their light flux, and can operate specified programs, provide color-music accompaniment. Group S. halogen lamps In the design chandeliers provide basic lighting, and the LED performs the flowering effects.

It is best to buy chandeliers complete with remote control and not complicate your life. Now many manufacturers make such products, it will ensure warranty and detailed schemes, instructions how to connect a chandelier with a remote control.

You need to choose a model controlled by radio channel, unlike the infrared signal transmission channel there is no need to direct the remote control towards the chandelier. For the radio channel, the conditions of direct visibility of the chandelier are not required and do not matter various obstacles, walls or furniture, the range of action is much larger. From any point of the house or the territory of the yard can be controlled lighting. Some consoles work at a distance of 100 m.

Working in a pair with a receiver at one frequency, the remote controls the signal to the controller, which sets the flagrafovy effects by the installed program.

In most cases, the radio signal receiver and the controller constitute one block in a single case.

Connection sequence

The lighting group is dealers, the corresponding machine on the introductory device is turned off. A switch is dismantled, there will remain three wires in the wall, total and two on groups of lamps chandeliers. To determine the general wire, the easiest way to mark it before removing the switch, it is easy to determine on the contacts. When you switch the keys, the remaining 2 contacts are closed.

For remote control systems, where there is no basic console, you can leave the switch in the permanent position or dismantle, closed the shared wire with one of the two remaining. All ends to draw and close the box with a decorative lid or attach.

The overall wire on the ceiling is desirable to mark when dismantling the old chandelier or to remove the switch to determine the multimeter. The device is placed in the measurement mode of the variable voltage to the scale limit above 220V. Control probes are connected to two of the three wires. Including the switch keys, you need to watch, there is a voltage between which wires. If there are no voltages, the remaining unconnected to the multimeter will be common.

The scheme for determining the general wire on the chandelier

There are several ways to define a common wire. Instead of a multimeter, you can use a test lamp. An indicator screwdriver can be checked by the phase when a phase is fed from the switch to the lamp, when you turn on both of the switch keys on two wires, the indicator will light up. In general, the indicator screwdriver will not show anything. When the phase is connected to the general chandelier wire, the indicator will immediately show it, the screwdriver indicator will not shine on the other remaining.

After determining the general wires on the switch and the ceiling, the switch to the base stationary remote control changes. It is necessary to feed the 220V power on it, for this you need to dismantle the switch and dilute the three wires in different directions.

All do it with a disabled network. On the ceiling, in the location of the chandelier, the shared wire is bridged with one of the two connections from the switch.

Next, the power is connected, the multimeter is determined, between which wires of the switch will appear 220V voltage. These two wires are connected to the terminals L and N stationary control panel, the remaining wire on the OUTPUT terminal.

Inpatient Console Connection Scheme

After that, the housing of the stationary console is placed in the location of the switch.

Dual and single wires on the ceiling are connected to the controller:

zero on terminal n;
phase on terminal L and shared wire of lamps.

Connection chandelier circuit to controller

After assembling the circuit in the chandeliers, all the lighting elements are screwed down, then the power is connected, the performance of all modes is checked while controlling the lighting from the remote and stationary consoles. During normal operation, the voltage is turned off and the installation of the chandelier on the ceiling is completed.

Console for chandelier. Video

About the convenience of setting up and using a chandelier for a chandelier tells the video below.

From the above information it follows that a chandelier with remote control of any model can be connected independently. But at the same time it is necessary to remember the safety measures. For incomprehensible issues should be consulted with experienced specialists.

Instruction

Select the model of the universal console, purchase the device and prepare it for use. You can pick up batteries of the desired size, as a rule, they need no more than two AAA types. Remove the battery compartment cover, observing the polarity, insert the batteries into the remote control. Close the power supply and take the instruction. Carefully read the device's instruction manual, codes should be inscribed in it. different firms Manufacturers household appliances. Find the values \u200b\u200brequired for your instance. As a rule, there are several such codes. Select the desired and enter them in accordance with the manufacturer's recommendations. If necessary, for example, if you can not understand some specific terms, learn on the forums on the Internet. There are many sites where it is described what settings you need to perform and users in discussions can ask questions, receive answers to them.

Universal remote Works on the same scheme as a control panel to a specific technical device, regardless of whether it is a kettle with remote access. The device is a small box equipped with buttons or display, contact LEDs and electronic circuit. By pressing the "Start" button, the infrared transmitter sends a specific "code" to the same receiver of another device and, accordingly, performs the command you need - adjusts the volume, adjusts or switches the specific channel.

After you entered the required code on the remote control, simultaneously press the SET and TV keys (sometimes instead of TV on the device, DVB is written). If the code is correct, the indicator on the POWER key will light up. This is an indicator that the device functions and is ready to manage. The remote does not perform the functions declared by the manufacturer? Try entering a different code value and try to use it again. In this case, will help you automatic search. Enable the technique you want to control using a universal console. At the same time, press the SET and TV keys and keep them within a few seconds until the Power key indicator starts flashing. The color of the signal depends on the model of the universal console, but most often it is red.

Direct the remote control. If your universal console reacted, quickly press any key except SET. If you did not have time to do this, run a newly automatic search or go to manual setting. Using such manipulations, you set the signal set very quickly.

Try to configure the control of the universal switch using manual search. For example, turn on the TV, adjust the desired channel. At the same time, press the SET and TV keys until the POWER key indicator lights up. After that, alternately press this button until the TV starts responding to the remote signal. Pauses between clicks should be no more than 2 seconds. To complete the search, press the SET or TV key.

Check the performance of the configuration. Try with the remote control to adjust the sound, switch channels, turn off the device. If all operations are performed, the installation and the work of the console is carried out correctly.

Similarly, you can configure a universal remote to work with other devices. Instead of the TV button, clamp and hold the button corresponding to the configurable device before the start of the LED flashes. For example, DVD for DVD player, SAT for satellite receiver etc.

Depending on the manufacturer, various recommendations on the use of settings codes will be given in the instructions for the universal console. For example, in the English version, the codes are located in the Brand section. In the domestic - developers allocated a separate chapter in Russian. Choosing a universal remote control to control the technique, pay attention if the management in Russian.

The universal remote can be used not only to configure home appliances, it is easy to control even a car. But for this you need to make adjustments in the settings. Try also to use the technical device by driving them to turn on or off the light in the apartment, the opening of electronic locks, in general, where remote control is possible. Such an assistant is conveniently used in the kitchen.

If you do not use this moment Technique or plan to leave, first remove batteries. In no case do not allow contact technical device With water, it is also impossible to drop the remote control, the circuits located inside can be easily damaged during the fall and the universal remote control will be released from the device. If this nevertheless happened, contact the repair service, since this technique also has a guarantee, most often at least six months.

In the general case, remote control (PD, RCU) - wireless or wired devicedesigned to manage any mechanism, object or process at a distance. All devices are divided into groups:

by the method of producing power: on the cable, autonomous;
according to the channel used to transmit control signals: IR, ultrasound, radio, wire, mechanical drive;
by functionality: with one set of commands, universal for several devices of one manufacturer, programmable (trained);
mobility and other features.

The most common appearance of the remote control is a mobile autonomous wireless device with controlling objects by infrared channel (IR). It is such a type of device devices that use in everyday life when we transmit control signals to the TV, air conditioning, music Center, player and other household appliances.

In the first models of the consoles, there was a minimum of control elements only to perform basic functions. Over time, the approach has changed: modern products have full set controls, and managed devices themselves contain their limited set.

Remote control device

The gadget is a small oblong plastic box. On the front part of it, the buttons are located with which the control command is selected.

At the end of the device there is a hole for an IR emitter lenses, which directly sends the command to execution. From the reverse side, under the lid, a niche is located for installing batteries. As a rule, these are two AAA batteries.

If you disassemble the remote, disconnecting its upper part from the bottom, then we will see two more elements. First - printed circuit board with contact venues and mounted electronics.
The second is made of soft elastic material with convex control buttons with conductive disks.

Infrared Wireless Remote Control: Operation Principle

The remote control device and the operation of the remote control are based on one-sided or bilateral transmission of information between the console and the control object using light rays in the infrared range. IR receivers and transmitters are used for receiving and transmitting signals.

The circuit with a two-way transmission channel of information has the consoles controlling air conditioning: a control signal is sent to the air conditioner, and the parameters of the unit and temperature data are sent back.

All other models in the overwhelming majority are single-channel cases.

Transfer and reception of commands

Take the operation that most often meets in everyday life: remote wireless control TV. The first thing that makes the panel scheme determines which button is pressed. The principle of determining the same as in computer keyboard: Scanning the matrix of the placed buttons. But, unlike the PC keyboard, on the remote control scan Generator It is in standby mode and turns on only when the buttons are pressed on the remote. This is achieved economical use Elements of nutrition.

Then the control signal (command) and the transmission of its IR LED is coding. Before transferring the main signal, synchronization of the transmitting and receiving devices is synchronized, and the consistency of the console code is checked on the receiving side. The transmission itself will be carried out for the entire time while the control button is pressed.

It should be noted that manufacturers electronic devices Not limited to the creation of algorithms for coding control signals and the modulation frequencies used. This leads to the fact that often even single-type models of one manufacturer require different control panels to control.

Remote control panel

Most of the control panels of TV and other household devices are based on basic microcircuitgenerating control signal after pressing the corresponding key, signal amplifier and IR LED. The difference lies only in the name and layout of radio elements inside the device housing and on the printed circuit board.

The microcircuit is a specialized microcontroller, in which in the production process is recorded program code. The recorded program is then no longer changed during operation. On the board is also located quartz resonator To synchronize the frequency of the receiver and the transmitter. The signal amplifier is included in the microcircuit or is made on a separate element.

To independently create such a device, except for radio skills, you need to be able to create a software code for microcontrollers.

PC Remote Control

Remote control for personal computer may be useful when working with an interface like the most operating systemand when managing the functioning of various programs. For example, managing presentations in POWER POINT. or reproduction of media content in Media Center.. Sometimes such consoles are already included in the PC.

Manufacturers of the PCs, unlike TV, implemented 2 solutions: IR and radiopulists. The fact is that stably when controlled in the infrared range interacts with the device with direct visibility and at a distance of up to 10 m, which is sufficient for TV, but it may be inconvenient to control the PC, especially during presentations. Radiopult increases this distance to 30 m regardless of the obstacles to the signal path.

Externally, the radio round from IR will differ only in the presence of a small antenna. But in order to manage, the PC is needed another item: a radio or ik signal receiver installed in a computer or laptop. It can be like a built-in device and a module connected to uSB port. The second option is preferable.

Universal and / or programmable remote control

The universal remote control may be required in two cases:

No replacement is found for the lost or failed TV control or other household appliances.
Many different household appliances in the same room makes control of it from different removes extremely inconvenient, since the concept of "proper design" and "optimal ergonomics" from all manufacturers.

There are two types of devices: consoles, memorable commands (students), and programmable universal remote control. In the first case, a regular remote control of the TV or other device is used to enter the desired codes. In the second, a list of available codes and models of techniques that can be managed, is in the instructions for the control. The difference is that, despite thousands of models of devices supported by universal consoles, the desired device This list may not be.

"Training" of storage control panels is made in accordance with the user's manual and using the original remote control. If the acquired remote has a smaller number of keys on its front panel than that of the "native", then first of all it is necessary to program only those that are necessary.

After the acquisition of a universal multifunctional console should not throw old regular. First, they may be required if the new will suddenly fail. Secondly, the universal may not be some of the necessary elements. And thirdly, they may be required to reprogram in the event of a failure or change of batteries.

Smartphone as a remote

Another variant of the remote control is almost for any device - using the smartphone as a control device. In this case, it may be, and may not be implemented to transmit signals in the IR range (technology Irda.). In the latter case, control is carried out via Bluetooth or Wi-Fi. The only limitation is that the managed device should also support these information exchange protocols, which is not implemented on all technique.

More interesting as a remote version of a smartphone with an IR port. Consider this on the example of the model Xiaomi Redmi 3. and pretty old tv Daevoo.. We will need to establish from Google Play. special application. It can be any, the main thing is that the model of the control object should be needed in the list of supported equipment. For this phone with a shell from Miui. it's called Mi Remote. (Russian is present).

This type of lighting is actively used in residential, office and even industrial premises. The highest popularity today received control systems implemented using radio shutters, motion sensors, controllers with control panels, smartphones and computers. Modern technologies allow you to manage or at the railway site, being, being hundreds of kilometers from them. Some of them will be discussed in the article.

Advantage of remote control

The use of remote control devices allows you to solve a number of tasks:

Economically spending electricity;
Make the process of incorporating / disable lamps as comfortable as possible;
Musture your home or apartment from attacker's encroachment (presence effect).

Types of remote control

Remote light inclusion is wired and wireless, manual and automatic, with the possibility of manipulating light from devices operating on the principle of radiation and reception of waves defined frequencies: infrared, microwave, radio frequency, sound, ultrasound, voice (managing specific teams). This article will focus in detail on the lighting management using of different types radiation, voice and sound commands.

Infrared and radio wave control light from the console

Infrared lighting control using the console is extremely rare. Basically, such systems work on the principle of transmitting the signal over the radio channel. For the possibility of manipulating light instruments with an IR beam, a remote lighting control unit is connected to the chain rupture, such as BM8049M. It allows you to turn on the lamp with a regular remote control from the TV. To do this, the remote control is attached to the block, they hise any key (which is not used to switch channels), after which the command is written in memory and now it is possible to control the power on, without getting up from the sofa.

The main disadvantages of using IR remote control lights are the need to accurately hover on the signal receiver, as they work only within the limits of direct visibility, and the small range of ray, but in this case you can use repeaters.

Much more distribution received light control systems using the remote control, in which the signal is transmitted from the control device to the controller, regulating the power on / off of light on a certain radio frequency.

The light control over the radio channel is more in demand for several reasons:

The ability to control the light not only the console, but also a computer, smartphone and other devices;
The radius of the signal is about 100 meters in the absence of obstacles, 15-25 meters in the presence of obstacles;
The ability to set the signal amplifiers and repeaters for best transmission commands from the control device.

The remote control system by radio channel using the remote consists of:

Console;
Battery;
Remote control controller connected to the network and load.

Install the controller into a wall or a glass of chandeliers (see photo). They can be controlled by incandescent lamps, compact and conventional fluorescent, halogen, lED lamps, not only by single luminaires, but also by their group.

Overview of the remote control of lighting, Chinese production, with the remote control, by radio channel, video:

Remote light control with infrared and radio switches

Infrared switches are rare on the market of lighting, as it is wiser to control the light using radio devices. One of the most popular switches - Sapphire Company of Nootekhnika (Belarus). The same company releases a variety of lighting control devices by radio channel, including those mentioned below. The switch is controlled by any console, such as television or manually. Receives signals receiver located inside the device on touchpad. Light switch with remote control is presented in the photo.

Overview of the Sapphire IR switch, video:

The light switch with remote control is located in any place convenient for themselves, power blocks - in a distribution box or a cup of chandeliers.

An example of "binding" block of lighting control to the radio switch, video:

Using lighting control sensors

On the market lighting are widely represented various sensors Movements for remote lighting control. The most common is infrared. They are devices, closing or discharging lighting chain with an increase in the level of infrared radiation in the zone of their "visibility". As soon as a person or an animal fall into the sensor field, the body temperature is above the background temperature - the light turns on. As soon as a person leaves the zone of the sensor or a few seconds is in a fixed position - the light turns off. Motion sensors are mounted most often in the entrances, above the entrance door, less often - inside the apartment.

Disadvantages and advantages of infrared sensors

The disadvantages of the use of motion sensors include the possibility of false positives (reaction to warm air, sun rays), deterioration in the street on the street due to atmospheric precipitation, lack of an instrument in the case when man's clothing does not transmit infrared radiation, constant light turning off after 10-15 Seconds as soon as motor activity decreases.

The benefits of sensors include the ability to control the consumption of electrical energy and as a result of reduced money, safety for human health, ease of use.

Connection of motion sensors does not cause difficulties, the installation scheme presented below is very common. To implement it, a three-cable wire is needed to which the lighting control device is powered by the network and is connected to the load. The phase wire wire is connected to the sensor phase wire. Zero conductors of the lamp, the power supply and the sensor are connected together. The lamp with phase wire is connected to the remaining sensor wire.

Selection of infrared motion sensors

When choosing IR sensors draw attention to the following parameters:

Place of application. Sensors are manufactured with the degrees of protection from IP20 to IP 55 and are built and attached. For use in the apartment, it is more profitable for an embedded sensor, and the degree of protection practically does not play roles. To install the device on the street or in the stairwell, it is better to choose a model with protection against dust and water installed on the bracket;
Maximum range. IR sensors capture the change in the background temperature at a distance of 10-20 meters. Those of them that plan to install on the street should have a larger radius of "coverage". In the room this parameter for nothing;
Detection angle. In the vertical plane, the angle of view of the sensors - 15-20 degrees, in horizontal - from 60 to 360 degrees;
Load power. Before buying a sensor, you need to know the power of the load connected to it and select the device for these indicators with a margin.

Using other motion sensors to control light

In addition to infrared regulators, microwave, sound and ultrasonic, and combined sensors are sometimes used to control lighting.

Microwave sensors

Microwave sensors operate on the principle of radiation and receiving electromagnetic waves. In the usual mode, the frequency and length of emitted and reflected from the objects of the waves are the same. When a person fall into the sensor zone, these parameters are changed, after which the switching mechanism of the light chain is activated. The advantages of microwave sensors are that they are high-precision devices, work perfectly even with bad weather, and flaws are the possibility of false positives, high price, harmful radiation from sensors with a large radius coverage.

Ultrasound sensors

Ultrasonic sensors on the principle of operation are similar to microwave sensors. Inside these devices, a sound wave generator is set, a frequency of 20 to 60 kilohertz, which is emitted and reflected from objects located in the sensor action field. When a person or an animal hit in a radius of coverage, the frequency of the sound waves coming to the sensor changes that the device immediately registers. Disadvantages of ultrasound sensors: may not react to smooth movement, cause discomfort in animals. The advantages of the sensors: low cost, work in conditions of high humidity, temperature changes, react to movement, regardless of whether clothing from which material on person.

Combined sensors

Combined sensors combine several motion detection technologies. They can use microwave and ultrasound radiation or infrared and microwave. Such devices are most qualitatively performed in front of them tasks.

Sound sensors

Sound sensors react to a sharp change of sound, the level of which is set by changing the sensitivity of the sensor. Most often include and disconnect the light with cotton in your hands. Voice switches can be considered a variety of sound sensors.

Voice control light

Voice control of light instruments in the apartment is implemented using voice sensor-switches frequently used in systems " Smart House", As well as computers or smartphones on which a special program is installed.

Light switches with remote control (voice) are divided into two types: with the need to configure and without it. In the first case, you need to train the device to command the activation, turn on and off, in the second case, all commands are already spelled out in memory and are specified in the instructions, you just need to use them to control. Often, such switches can be controlled not only by voice, but also by any console. These include "Jaco" and "service." You can get acquainted with the features of their work on the sites of manufacturers.
