Product description

The motion detector is used for automatic, temporary lighting attach if a person or another object appears in detector’s range in places such as hallways, courtyards, approaches and driveways, garages, etc. 
With presence detector function.
The DRM-08 sensor can work as a presence detector.
Microwave sensor allows for motion detection by wooden boards, plasterboard panels, glass and plastics.

The DRM sensor emits and receives 5.8 GHz high frequency electromagnetic waves. The sensor detects changes in wave reflection caused by the movement of the object in the detection area. The sensor detects movement of the object to and from the sensor. Movement in the detection area automatically switches on the lighting. From the moment of switching on, continuous movement causes the lighting to stay on permanently. Only lack of movement in the detection area triggers the lighting back-up time. Another movement in the detection area and its disappearance during the countdown will start the back-up time from the beginning. The nature of the operation allows the DRM to be used as presence sensor.
After the preset time, the lighting will be switched off automatically. The motion sensor is equipped with a twilight sensor  that prevents the controlled lighting from being switched on during the day. The detection status and the readiness to switch on the lights are activated only after dark. Activation time of the sensor can be adjusted by the user through a potentiometer. In addition, it is possible to adjust the detection area in the radius range of 1÷8 m (for h=2÷6 m) and to adjust the time of the receiver in the range of 10sec÷12min. The motion sensor can work indoors. The sensor allows to detect movement through wooden boards, plasterboard panels, glass and plastics. Temperature changes do not affect motion detection.


The power of microwave radiation is relatively low and is completely safe for humans and animals. Its value is less than 0.2 mW. By comparison, microwaves and cell phones radiate about 1000 mW of power (100 times harder).
