This affordable and widely-used module emits ultrasonic waves and measures the time it takes for the sound waves to reflect off an object and return. With a working voltage of 5V, it is compatible with most microcontroller boards like Arduino and Raspberry Pi. The module can measure distances from 2 cm to 400 cm, with an accuracy of ±3mm, making it perfect for robotics, obstacle detection, and distance sensing applications. The HC-SR04 uses a trigger and echo system: the trigger pin sends a signal, and the echo pin receives the reflected signal, calculating the distance based on the time taken for the pulse to return. This sensor operates in the 40 kHz frequency range, ensuring precise and reliable measurements in most environments.
