Plafond with microwave motion detector DRM-04

Microwave sensor allows for motion detection by wooden boards, plasterboard panels, glass and plastics.

Functioning
DR sensor emits and bounces high-frequency 5,8GHz electromagnetic waves. The sensor detects changes in the reflected waves caused by movement of an object in the area of detection. The sensor detects movements of an object to and from the sensor. Movement in the range of detection will automatically switch ON the lighting. Since the moment of lighting is switched, continous movement in detection area causes permanently lighting switch. Next move in detection area and its loss during the time countdown will start the time of sustain from the beginnig. After this time lights will switch OFF automatically.The motion sensor is equipped with light dependent relay which not able to attaching lighting during the day. Detection status and stand-by to switch ON lights are activated after dusk. Sensor activation time might be adjust by the user. In addition, there is possibility of adjustment of the detection area in range 2-10m(for h=2,5m) and the receiver actuation time adjustment to 5sec-20min. 
  
 

ATTENTION!
The power of microwave radiation is relatively low and is completely safe for humans and animals. Its value is less than 10mW. By comparison, microwaves and cell phones radiate about 1000mW of power (100 times harder).
