Parking Sensors and Reversing aids

Parking Sensors/Reversing aids are fitted sensors placed into the rear bumper of your vehicle.Each sensor sends out an invisible and harmless beam of ultrasound that is reflected by an object.The system monitors the returning pulse and converts the reflected sound waves into measurements of distance. An audible sound then lets you know how far away from the object you are, when you get to 30cm away from any object, the tone increases in sound the closer you get to the object telling you to stop
