This tutorial is about how to use Ultrasonic Sensor HC-SR04 with Arduino UNO, The Ultrasonic HC-SR04 sensor uses SONAR to determine the distance to an obstacle or an object like Bats, an excellent digital non-contact range detection with high accuracy and stable reading. From 2 centimeter to 400 centimeter. The operation is not affected by any light or a colored objects it has a sharp rangefinder although acoustically soft material like cloth can be difficult to detect. it has a complete sonar powered Ultrasonic Transmitter and Receiver Module, Tested in Arduino, Raspberry Pi and Common Micro Controller.
