In contrary to passive infrared motion detectors, which only register objects with a temperature difference to the background, radar motion detectors 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 supplies a non-amplified mix signal (FMCK/FSK) which has to be processed in a following amplifier circuit before it can be evaluated by a comparator or a micro controller. The radar sensor is suitable for detction of movement, velocity, presence, direction and distance.
Typical areas of application:
- Level measurement
- Sanitary appliances
- Alarm and security applications
- OEM applications
- Automotive
