HC-SR04 Ultrasonic Range Finder – Accurate Distance Measurement Sensor The HC-SR04 Ultrasonic Range Finder is a widely used and reliable distance measuring sensor module designed for a range of applications that require object detection or distance measurement. This module features two “eyes” — one acts as a transmitter and the other as a receiver. It uses ultrasonic sound waves (similar to sonar used by bats and dolphins) to determine the distance between the sensor and an object. The HC-SR04 integrates a transmitter, receiver, and control circuit in one compact package, ensuring excellent accuracy and stable readings. It is unaffected by sunlight or color variation, making it ideal for use in diverse environments. With a detection range of 2cm to 400cm and an accuracy of up to 3mm, the HC-SR04 is perfect for precise distance sensing in robotics and automation systems. It can be easily connected to a microcontroller or Arduino via its Trigger and Echo pins. Whether you’re designing a robot obstacle avoidance system, a distance meter, or a smart parking system, the HC-SR04 ultrasonic range finder ensures dependable performance every time.
