Garage Door Photo Eye

Garage door photo eye is a small, flat, blank square that sits in front of the garage door and sends an infrared beam across to the other side. If something blocks that beam, it means something is in front of the opening and you need to stop and move it out of the way. When people think about these sensors for garages, they are often thinking about automobile safety. After all, if you don’t see a car coming as you go to back out from your garage or driveway because there’s something blocking your view of oncoming traffic—that could be fatal.
