Microwave Occupancy Motion Sensor for Light Fixtures

When a warm moving object such as a person or automobile passes through the field of view of the internal motion sensor, the light turns on from 5 seconds to 6 minutes (adjustable)  During the day (when used outside) the built in photocell prevents automatic operation, saving you energy.

This microwave occupancy sensor uses ultra-high-frequency radio waves and uses the Doppler Effect to detect to detect motion.  This extremely safe method that bounce off radio waves of nearby surfaces and then return to the sensor, and works even when the sensor is placed inside most fixtures. No direct line of sight to the device is necessary!
