HC-SR04 Ultrasonic sensor interfacing with PIC Microcontroller

In this tutorial we will learn how to works the HC-SR04 Ultrasonic module and how to use it with pic microcontroller. The HC-SR04 Ultrasonic module is a contactless distance measurement sensor. It can measure distance from 2cm to 400cm with are ranging accuracy up to 3mm. The HC-SR04 module has two part Ultrasonic Transmitter and ultrasonic Receiver. The Transmitter emit the ultrasound and receiver receives that the reflected sound. It operates 5 volt DC supply.
