Distance Measurement using HC-SR04 and AVR Microcontroller In this tutorial we are going to discuss and design a circuit for measuring distance. This circuit is developed by interfacing ultrasonic sensor“HC-SR04” with AVR microcontroller. This sensor uses a technique called “ECHO” which is something you get when sound reflects back after striking with a surface.

Distance Measurement using Ultrasonic Sensor and Arduino Ultrasonic sensors are great tools to measure distance and detect objects without any actual contact with the physical world. It is used in several applications, like measuring liquid level, checking proximity and even more popularly in automobiles to assist in self-parking or anti-collision systems. Previously, we have also built many Ultrasonic Sensor… |
