In contrary to passive infrared motion detectors, which only register objects with a temperature difference to the background, radar motion detector modules react to all kinds of movements towards the sensor. The motion sensitivity is very high, even the smallest movements are detected.
The radar motion detector module supplies a non-amplified mix signal which has to be processed in a following amplifier circuit before it can be evaluated by a comparator or a micro controller.
Typical areas of application:
- Level measurement
- Sanitary appliances
- Alarm and security applications
- OEM applications
- Automotive
