Summary of Microwave Motion Sensor Module

Microwave Motion Sensor Module is Developed applying Doppler Radar principle.
The role of Sensor Module is transmitting a low power Microwave from transmitting antenna and receiving the microwave energy reflected by objects to receiving antenna.
If the movement of the object is detected by the microwave motion sensor, the reflected microwave frequency is shifted away from the transmit frequency to receiving antenna.
The reflected and shifted microwave frequency is mixed with the transmit microwave frequency and results a low frequency voltage at the output of the sensor.
