How do Backup sensors work?
Backup Sensors: “Back-up Warning. Alerts you of objects behind your car as you back out of spaces like driveways or parking spots. What It Does: Uses rear sensors to scan for objects behind your car and alerts you if one is detected.”
Many vehicles on the market come with this useful feature called a back up sensor which makes a sound when you're getting too close to something or about to crash, this feature was designed by manufacturers to help avoid hitting objects when backing up. There are a few backup sensors and they all work similarly; they use either magnetic or ultrasonic sensors that transmit waves which bounds off objects and when returning they let the computer know how close you are to an object and how big the object is even if the object is moving toward you. Here at Bcr Automotive many of our vehicles come with backup sensors which is an excellent feature to avoid accidents.
