Ultra Sonic Sensor Module Hc-Sr04 is an ultrasonic ranging sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit. There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground).

The basic principle of work:

  • Using IO trigger for an 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
