With presence sensor function.
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. Since the moment of lighting is attached, continious movement in detection area causes permanently lighting attach. Next move in detection area and its loss during the time countdown will start the time of sustain from the beginning. The way of functionning allows to use of DRM as a presence sensor.
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).
