Detailed Description

Ultrasonic Distance Sensor HC-SR04

Ultrasonic Ranging Module HC-SR04

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).

You will find this sensor very easy to set up and use for your next range-finding project!

This sensor has additional control circuitry that can prevent inconsistent "bouncy" data depending on the application.

Features:

  • Operating Voltage: 5V DC
  • Operating Current: 15mA
  • Measure Angle: 15°
  • Ranging Distance: 2cm - 4m
  • Quiescent Current : <2mA
  • Resolution : 0.3 cm
  • Trigger Input Pulse width: 10uS
  • Dimension: 45mm x 20mm x 15mm
