Ultrasonic Distance Sensor - HC-SR04

CED-SEN-15569

This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. 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
