Motion Detectors

By: Davis Deussen

In schools, they use motion detectors to turn off the lights if they do not detect motion for 30 minutes. So, if someone forgots to turn the lights off, and they leave, the motion detector does its job to turn off the lights, and it saves energy. I believe that it should just be 5 minutes to save more energy and more money. These small things make the world go round.
