Enjoy advanced energy savings and state-of-the-art automation with Eaton’s occupancy and vacancy sensors. Eaton's motion sensor lighting controls use advanced Passive Infrared (PIR) and ultrasonic sensing technology to detect your presence and switch lights ON. Then, once you’ve left the room, our sensors turn the lights OFF following a preset period of time. Sensors are the perfect solution for commercial and residential applications where a switch is inconveniently located and in spaces where lights may be left on accidentally.
