HCSR04 is an Ultrasonic ranging module which consists of a transmitter, receiver and control circuit. It has four pins for VCC, GND, Trigger, and Echo. You can easily interface it with microcontrollers and Arduino boards.
The basic principle of work is: Using IO trigger for at least 10us high-level signal, The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.IF the signal back, through high level, time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level time×velocity of sound (340M/S) / 2.
