  1. 2008/11/27 KMY10 - Microwave Motion Sensor
The KMY 10 is a microwave rader motion sensor based on the Doppler effect. It transmits a low energy microwave radiation at 9.35 GHz which is reflected by objects. If the object is moving relative to the sensor, a Doppler shift occurs. The shifted wave is mixed with the original wave, resulting in an output voltage.
