Motion Sensor Cover

When I moved into my dorm at Cedarville University, lots of people had issues waking up in the middle of the night due to people walking around in the hallway in the middle of the night which triggered the motion sensor lights. There is a big gap under our dorm rooms which lets in a bunch of light. Taping over the motion sensors wasn't allowed, so I designed these moving covers which have been in use for at least three years now.
You may have to experiment with scaling for the attachment brackets, as well as gluing them to the outside cover for sturdiness.
