ABSTRACT: This paper describes an ultrasonic sensor that is able to measure the distance from the selected points of a motor vehicle. The sensor is based on the measurement of time of flight of an ultrasonic pulse, which is reflected by the obstacle. The sensor is composed of only low-cost components, thus being apt for distance measurement in many cases, and is able to self-adapt to different conditions in order to give the best results.
