How to adjust the motion sensor for lighting?

Manual inclusion of light is not always convenient not only in a commercial enterprise, but also at home. To automatically turn on the lighting, special sensors-indicators are used, capable of recognizing a person in the range of their action. The motion detectors of ultrasonic, microwave and infrared types are used both in residential and public buildings. After reading this article, you will receive an answer to the question: how to adjust the motion sensor for lighting?

Classification, or which sensors to illuminate better

As already mentioned, according to the principle of operation, the detectors are distinguished by:

• ultrasonic;
• infrared;
• microwave;
• mixed.

Let's look at their differences to find out the difference in the principle of action, and accordingly - which sensors are better for lighting.

Infrared

Infrared detectors react to the thermal radiation of the human body. The receiver responds to infrared rays. The infrared signal is converted to electric, the lamp contacts are closed, as a result, light is switched on.

There are passive and active sensors:

• The first react to the change in ambient temperature.
• Active devices scan the room.

When the signal is interrupted, the light is switched on.

Important! It is very important at the same time to avoid contamination of the receiver, the transmitter, since a false interruption of the signal can be caused by clogging.

Microwave, ultrasonic

Microwave and ultrasonic devices operate in a similar way, only their operation is caused by ultrasonic waves. Unlike infrared devices, the indicators of these two types can only be active( they constantly scan the room).

Important! The microwave device has the significant advantage that it can work "through walls".

The indicators differ also in the field of application - control of street or household lighting. They differ in their design."Street" detectors are enclosed in a protective case, which does not allow the penetration of dust and precipitation.

Important! In addition, devices designed for outdoor use have good anti-vandal characteristics. The household indicators do not have this option.

Tips for choosing lamps and sensors for lighting:

• For street work, LED spotlights are perfect. Lighting device perfectly tolerates temperature changes, almost does not break.
• In production, for lighting large areas, luminescent all-weather lights are beneficial.
• For household needs, twilight relays are convenient. These are sensors that react to both environmental changes and the degree of illumination of objects. With the onset of twilight, the device closes the contacts of the electrical circuit, which causes the light to turn on. This is a good solution for creating the effect of presence in the country.
• Different lamps can be used for street lighting, but experts recommend paying attention to diode energy-saving lamps.

Installation and setup of the

Now about how to adjust the luminaire with a motion sensor. There are many options for setting indicators on different surfaces. The simplest and, at the same time, reliable option - an infrared indicator mounted on the ceiling.

Important! Fixing the presence of a person in the range, the device works. If the object leaves the signal reception area, the detector opens the electrical circuit.

Wiring diagram of the luminaire with motion indicator:

1. The sensor has 3 cables: "lamp", "zero", "power".Specialists recommend, in addition to the sensor, to mount a conventional switch.
2. Connect the luminaire wire to the corresponding cable on the indicator.
3. Connect zero to zero of a conventional switch with a lamp.
4. Place the phase cable on the power supply network of the house or apartment.
5. Ensure that the connection of the pushbutton and the touch switch is parallel. Otherwise, an unstable traffic indicator with a sudden change in the voltage in the network will burn out.
6. After installing the sensor, check its operation. Repair, as well as planned reinstallation are done twice a year and more often to avoid incorrect operation of the indicator.

Important! This option is more suitable for setting the indicator indoors.

External devices are usually connected directly to the lamp:

1. A zero and a lamp wire are taken to the lamp.
2. Power is connected to the network cable.

Important! This scheme will suit both the apartment vestibule and the organization of access lighting.

Regarding the adjustment of the motion sensor for lighting, it is necessary to adjust the device in accordance with the instructions - each manufacturer gives its recommendations. Follow the rules, and you can do everything exactly as you expected.
