This is the HC-SR04 ultrasonic ranging sensor. Like like bats or dolphins the sensor uses sonar to determine distances. This economical sensor provides 2cm to 500cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. 

There are only four pins that you need to worry about on the module: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). You will find the HC-SR04 very easy to set up and use for your next range-finding project!

Features:
  • Power Supply :5V DC
  • Quiescent Current : <2mA
  • Effectual Angle: <15°
  • Ranging Distance : 2cm – 500 cm
  • Resolution : 0.3 cm
