Product Overview

The HCSR04 measures object distance using ultrasonic ranging. It offers incredible range accuracy and stable readings in a simple to-use bundle. It 's working isn 't influenced by daylight or dark material like sharp range discoverers are (delicate materials like fabric can be hard to distinguish).
The fundamental basic principle of operation is beneath, use IO port TRIG to trigger running. It needs 10 us abnormal state signal in any event module will send eight 40kHz square wave automatically and will test if there is any signal returned. In the event that there is signal returned, yield will be abnormal state signal through IO port ECHO. The span of the abnormal state signal is the time from transmitter to getting with the ultrasonic. Testing separation = length of abnormal state x sound velocity(340m/s)/2 You can use the above figuring to discover the separation between the impediment and the ultrasonic module.

Pin Description


Working Principle

  • The Ultrasonic sensor is designed to measure the distance using the principle of SONAR and RADAR, of using ultrasonic wave to determine the distance of an object.
  • The HC-SR04 sensor works on the exact same principle as the SONAR. The sensor has ultrasonic transmitter, receiver and control circuit to execute the given task, and the module consist of 4 pins and those are Vcc, Gnd, Trig and Echo.
  • An ultrasonic sound is to be produced to start the action. At least of 10µsec pulse has to be send through, and that is done by the Trig pin, then the Trig pin generates 8 pulses of 40KHz. After this the next step is to wait for the Echo pin to capture the generated ultrasonic sound to travel towards the object and return. It will measure the time that the ultrasonic sound took to come back.
  • The data collected by the above action (point no. 3), one can measure the distance of an object by using simple formula of measuring distance, using time of travel and speed of sound it air. Here the speed of sound is constant and the travel time data is collected by the echo pin.
