The main function of the ultrasonic sensor are transmitting and receiving. Ultrasonic sensors provide easy method of distance measurement. defined as electronic devices that emit an acoustic wave beyond the upper range of human hearing called the audible range, between 20 hertz and 20 kilohertz  and determine the distance between the sensor and an object based on the time it takes to send the signal and receive the echo. generic distance measurement, and commercial fish finders, among other applications.
