HC-SR04 Ultrasonic Sensor Guide
Posted by Kelly M on
The HC-SR04 ultrasonic sensor module is a very popular module for measuring distance or any other purposes. It emits an ultrasound signal at about 40 000 Hz which travels through the air and if there is an object or obstacle along its path, the sound will bounce back to the module. In this article, we will talk about how to wire and set up the module for operation with an Arduino Board. Wiring Most HC-SR04 modules operate at 5V and gives out digital outputs. For this project, we will be using the HC-SR04 Ultrasonic Sensor module we carry in our shop. This module consists...
