HCSR04 is an Ultrasonic ranging module that 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:

  1. Using IO trigger for at least 10us high-level signal
  2. The Module automatically sends eight 40 kHz and detects whether there is the pulse signals back.
  3. If the signal is back, through a high level, the time of high output IO duration is the time from sending ultrasonic to returning.
  4. Test distance = (high level time×velocity of sound (340M/S) / 2
