Parking sensors use a type of sonar. The term sonar is an acronym for sound navigation and ranging. It is used for calculating the distance and/or direction of an object from the time it takes for a sound wave to travel to the target and back.
An ultrasonic sensor emits and receives ultrasound. Vehicle parking sensors are equipped with this type of sensor. Ultrasound sensor is now evolving into an automatic parking system.
