HC-SR04 ultrasonic distance sensor module for non-contact distance measurement and obstacle detection in Arduino, robotics, automation and IoT projects.
The HC-SR04 Ultrasonic Sensor Module is a widely used distance measurement module that uses ultrasonic sound waves to detect objects and measure their distance. It transmits a 40 kHz ultrasonic pulse and calculates the distance based on the time taken for the echo to return.
The module provides simple Trigger and Echo interfaces, making it easy to connect with Arduino and other microcontrollers. It is suitable for robot obstacle avoidance, distance measurement, level detection, parking systems, automation and educational electronics projects.
