HC-SR04 Ultrasonic Sonar Distance Sensor Module for Arduino, Robotics & Automation

The HC-SR04 Ultrasonic Sensor is a reliable and affordable distance measuring module that uses sonar to detect objects from 2cm to 400cm. This sensor is widely used in Arduino projects, robotic vehicles, automated parking, level detection, and object avoidance systems.

It works by emitting ultrasonic waves and measuring the time it takes for the echo to return, calculating the distance accurately.
