HC-SR04 Ultrasonic Sensor Module
The HC-SR04 is a widely used ultrasonic distance sensor module designed for non-contact distance measurement. It operates by emitting ultrasonic sound waves and measuring the time it takes for the echo to return, enabling precise distance calculation. This versatile sensor is popular among hobbyists, students, and engineers for robotics, automation, and prototyping projects.
