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.
