Microwave motion detector DRM-02B

With presence sensor function.

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

Functioning
The DRM microwave sensor operates as a radar by using high frequency electromagnetic waves to detect movement in a monitored area. It is most effective when the movement takes place directly towards the sensor. In addition, the DRM has a built-in twilight switch that prevents the controlled lighting from switching on during the day. When motion is detected after dusk, the lighting will be switched on and will remain on as long as motion is detected. When the movement stops, the light remains switched on for a specified back-up time, after which it is switched off.
If motion is detected again during the back-up time, the cycle will start from the beginning. Due to its high sensitivity, the DRM can act as a presence sensor. The accuracy of the sensor
operation does not depend on the temperature. The detection range, the brightness level that activates the sensor and the time of operation back-up are set using the knobs described later in this manual. The sensor is designed for indoor use.
      

ATTENTION!
The power of microwave radiation is relatively low and completely safe for humans and animals. Its value is below 10 mW. In comparison, a microwave oven and a mobile phone radiate with a power of approx. 1000 mW.
