MPC-50V ceiling sensor is a 360° degree passive infrared (PIR) ceiling mounted motion detecting occupancy sensor. 

This ceiling sensor is ideal for warehouse, business or home use for the purpose of convenience, energy efficiency, security and surveillance. This occupancy sensor ceiling mount automatically turns lights ON/OFF when it detects motion and ambient light level. This ceiling sensor Includes two gray wires (22AWG) for connecting the unit to a momentary switch. 
Great for any bathrooms, warehouse aisles, or even businesses where you need a motion detector.
