Our project (Lights Out) addresses the problem of wasted energy caused by having all lights on in a room when it is only occupied by a small number of people in a small area of the room, in addition to addressing the problem of lights shutting off while people are working and not actively moving around the room triggering current motion detection systems. We plan to improve light motion detectors in classrooms/labs/office spaces by combining audio localizing technology with motion detecting sensors to only turn on lights in specific occupied section(s).
