How to Make Backup Sensors for Your Car

Back Up Sensors

The most common vehicle reversing aid is an audible sensor system. Back up sensors install in the rear bumper and have a speaker that changes beeps as your close in on an obstruction.

Backup sensors are motion activated detectors that alert drivers and/or pedestrians, by beeping/chirping when objects are too close behind a particular vehicle in reverse. These sensors are often utilized in conjunction with a wide angle camera, LCD monitor, or LED display.
