HC-SR04 Ultrasonic Ranging Module - (AD830)

Description:

This is the HC-SR04 ultrasonic distance sensor. This cost-effective sensor provides non-contact measurement functionality from 2 cm to 400 cm with a ranging accuracy of up to 3 mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver, and a control circuit.

There are only four pins you need to worry about on the HC-SR04: VCC (power), enable (activate), echo (receive), and ground (ground). You'll find this sensor very easy to set up and use for your next range-finding project!

This sensor has an additional control circuit that can prevent inconsistent data "bounce" depending on the application.
