Parking sensors definition and meaning

Parking sensors are devices that emit sound waves in order to detect objects behind a vehicle. These devices can be very useful in helping to avoid accidents, especially when backing up. Parking sensors are usually installed near the bumper of a car, and they work by emitting sound waves that bounce off of objects and then return to the sensor. The sensor then calculates the distance between the car and the object, and this information is displayed on a screen or spoken to the driver through a speaker. Parking sensors can be very helpful in avoiding accidents, but they are not perfect. It is still possible for a driver to misjudge the distance between their car and an object, even with parking sensors.
