Microwave motion sensor with presence sensor function DRM-01 DRM-01

The DRM sensor emits and receives 5.8Ghz high frequency electromagnetic waves. The sensor detects changes in the reflection of the waves caused by the movement of the object in the detection area. The sensor detects the movement of an object to and from the sensor. Movement in the detection field automatically turns on the lighting. From the moment of switching on, continuous movement causes permanent switching on of this lighting. Only the lack of movement in the detection field triggers the lighting hold time. Another movement in the detection field and its disappearance during the time measurement will trigger the backup time from the beginning. The nature of operation allows you to use DRM as a presence sensor. After the set time, the lighting will be turned off automatically. The motion sensor is equipped with a twilight switch that prevents switching on the controlled lighting during the day. The detection status and readiness to switch on the lighting are activated only after dusk. The sensor activation time can be adjusted by the user with a potentiometer. In addition, it is possible to adjust the detection field area in the radius range of 3-10m (for h=2.5m) and adjust the receiver activation time in the range of 5sec-12min. The activation of the receiver is signaled by the green LED. The motion sensor can work indoors. The sensor allows the detection of movement through wooden boards, cardboard-g boards, glass and plastics. Temperature changes do not affect motion detection.
