The sensor detects sound waves through a built-in microphone. It converts sound into an electrical signal and outputs a digital or analog signal based on sound intensity.
The sensor provides both digital and analog outputs. The digital output signals whether sound is detected (HIGH/LOW), while the analog output gives a voltage level proportional to the detected sound intensity.
The sensor's sensitivity can be adjusted using the potentiometer on the module. Turning the potentiometer clockwise increases the sensitivity, while turning it counterclockwise decreases it.
Connect VCC to the 5V pin, GND to ground, and the digital (D0) or analog (A0) output to an input pin on the Arduino. Use the analog input if you want to measure sound intensity, or the digital input if you're only interested in detecting the presence of sound.
