Retail price: $85.00

Our Price: $45.00 Per PC


The FM-105 high frequency occupancy sensor uses ultrahigh- frequency radio waves, also known as “microwaves” and the principle of the Doppler Effect to detect motion. The sensor sends out radio waves that bounce off of nearby surfaces and return to the sensor. Motion in the area changes the speed of the waves returning to the sensor. The sensor detects the change and interprets it as occupancy. This causes the sensor to turn ON the load. High freqency radio waves can penetrate..
