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.
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.
