HC-SR04 Ultrasonic Distance Measurement Transducer Module Sensor

The HC-SR04 Ultrasonic Distance Sensor Module is a highly accurate and easy-to-use device designed for non-contact distance measurement using ultrasonic waves. It provides precise distance readings by emitting ultrasonic pulses and measuring the time it takes for the echo to return after reflecting off an object. This makes it an essential component for robotics, obstacle avoidance systems, level measurement, and IoT automation projects.

With an effective sensing range of 2 cm to 400 cm and an accuracy of up to 3 mm, the HC-SR04 is widely used in DIY projects, industrial applications, and educational setups. Fully compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers, it offers a simple 4-pin interface for quick and reliable integration.
