Micro-wave Body Motion Sensor module

 (1) Radio wave (microwave) enables body motion sensing even at a distance from human.
 (2) Microwave penetrates through plastics and ceramic, etc., so the sensor module is able to conceal.
     (Window is unnecessary, so appearance of product is not damaged)
 (3) Sensing witdout influence of the surface temperature of the target and ambient light.
