Ultrasonic Distance Sensor Module HC SR04 – India

The Ultrasonic Distance Sensor Module (HC-SR04) is a popular Distance Measurement Sensor.  It’s basically a sonar, with one end emitting the ultrasonic wave and other end receiving, and based on the difference of emittance and arrival time it calculates the distance.

Working Principle of Ultrasonic Distance Sensor Module HC-SR04

  • The transmitter reacts to the voltage provided to the “Trig pin” and emits a high-frequency sound (ultrasonic) wave.
  • When the ultrasonic sound wave is intercepted by an object, it gets reflected towards the module itself.
  • The module receiver receives the transmitted sound wave and the voltage is sensed at the “echo pin”.
Although the sound wave is reflected in random directions by an object, the less effectual angle provides enough directionality to get some reflection in the direction of the module itself.
This module is very famous for Students, innovators, and  Faculties in India and worldwide who aim to use it for distance measuring in their autonomous robots without the use of a camera. For a quick User Guide click here.
