Description

The HC-SR04 sensor allows ultrasonic distance measurements between 2 and 450cm. It is a sensor widely used in robotic and RC projects based on Arduino, ESP8266, Raspberry Pi. It is also supported by ESP Easy firmware for ESP8266 WiFi modules.

The HC-SR04 has 4 pins. Two pins for the power supply (+ 5V, GND), a Trig Input pin (trigger input) and an Output pin (or Echo for some manufacturers) of the PWM digital signal. The output will deliver a pulse train proportional to the measured distance.

Technical characteristics of HC-SR04

  • Measuring range: 2 to 450cm
  • Measurement accuracy: 0.3cm
  • Supply voltage: 5V
  • PWM digital output
  • Weight: 9g
