Description
The HC-SR04 Ultrasonic Distance Sensor is a widely used and reliable module for non-contact distance measurement. It uses ultrasonic sound waves to detect the distance between the sensor and an object, making it perfect for robotics, automation systems, obstacle detection, and distance monitoring applications.
Compact and easy to integrate with Arduino, Raspberry Pi, or other microcontroller platforms, the HC-SR04 offers accurate distance readings from 2 cm to 400 cm, with simple 4-pin connectivity.
