This is a device to aid you in parking a car in a garage by providing a visual and audible warning. It is easily set up by mounting it onto the wall at the end of the garage.

The device produces a coded infrared (IR) beam which detects the proximity of the vehicle by bouncing IR off it as it approaches, without being confused by other IR sources. When the vehicle is within the preset range, an audible warning is given and a group of light emitting diodes (LEDs) are turned on.
