Radar Parking Sensors (Choice of Selections)

How do Parking sensors work?

Most new cars on the market today come with a combination of front, rear, and side ultrasonic parking sensors.

You can tell if these are fitted to your car by looking for small circles integrated into your front, rear or side bumpers.

They are normally body coloured, but can be another colour and they are normally spaced evenly apart.

Ultrasonic parking sensors work by emitting a high frequency sound wave (such a high frequency that it’s inaudible to the human ear), which hits an object and is then reflected back to the car.

The amount of time it takes for the sound wave to return to the car is then used to calculate the distance between the parking sensor and the object.
