Plafond with microwave detector DRM-03

Microwave sensor allows for motion detection by wooden boards, plasterboard panels, glass and plastics.
Functioning DRM sensor emits and bounces  high-frequency 5.8GHz electromagnetic waves . The sensor detects changes in the reflected waves caused by movement of the object in the area of detection. The sensor detects movement of an object to and from the sensor. Movement in the range of detection will automatically attach the lighting for time set by the user. After this time the lights will be turned off automatically. The motion sensor is equipped with Light dependant relay able to attaching lighting during the day. Detection status and stand-by to attach lights are activated only after dusk. Sensor activation time might be adjust by the user. In addition, there is a possibility of adjustment of the detection area in range 3-10m (for h = 2.5 m) and the receiver actuation time adjustment  to 8sek-12min. The inclusion of the receiver is signaled by a shining green LED. Sensor can work indoors. The sensor allows for motion detection by wooden boards, plasterboard panels, glass and plastics. Temperature changes do not affect on motion detection.    
 
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).
