What are parking sensors?
Parking sensors are small, round ultrasonic sensors usually located on a car's bumper. When you get close to an object, they measure the distance between the car and the object, letting you know as you get closer and closer with a series of increasingly shrill beeps. The quicker the beeps, the closer you are to the object.
