Occupancy sensors and light motion sensors aid in energy savings by dimming or turning off light fixtures according to vacancy or movement. Occupancy sensors detect when someone enters or exits a room. Motion sensors sense walking movement in a defined space. According to the Department of Energy, occupancy sensors can save anywhere from 10% to 80% in energy costs in offices, corridors, and storage areas.
Motion detector lights find use for both indoor and outdoor lighting. Solar powered, outdoor motion detectors can pair with a security camera to record when movement is picked up. After a sensor works in detecting the presence in an area, it coordinates with lighting controls to turn on/off or dim integrated LED fixtures. Some occupancy and motion sensors use passive infrared, ultrasonic sensors, or PIR sensors.
