HC-SR04 ULTRASONIC MODULE

 

Product information
Ultrasonic ranging module HC-SR04 provides 2cm - 400cm non-contact measurement. The ranging accuracy can reach 3mm. The module includes an ultrasonic transmitter and receiver as well as control circuitry.

The basic principle of how the module works:

  1. Pull the Trig pin high for at least 10us.
  2. The module sends a 40 kHz pulse and detects whether there is a return pulse.
  3. If there is a return pulse, based on the distance from the module the Echo pin will have a specific duration where the pin will be in a high state.
  4. Distance can then be calculated using formula Distance = (high level time × speed of sound (340m/s) / 2

Easy interfacing to a microcontroller as follows:

  1. VCC - 5V Supply
  2. Trig - Pulse Input
  3. Echo - Pulse Output
  4. GND - Ground

The HC-SR04 is good choice. Its stable performance and high ranging accuracy make it a popular module in the electronic market. Compared to the Sharp IR ranging module, the HC-SR04 is inexpensive but has the same ranging accuracy with a longer ranging distance.
