Product Description:

The HC-SR04 Ultrasonic Sonar Sensor is a reliable and affordable module for measuring distances using sound waves. It works by sending an ultrasonic pulse and detecting its echo to calculate the distance between the sensor and an object. This module is widely used in robotics, automation, and obstacle-avoidance systems due to its accuracy, simplicity, and low power consumption. It is fully compatible with Arduino, ESP32, Raspberry Pi, and similar controllers.
