This module detects sound levels via a built-in microphone. The LM393 comparator processes the signal, and when the sound exceeds the set threshold, the digital output goes low and the onboard LED lights up. The sensitivity can be adjusted with the potentiometer. The analog output provides the raw microphone signal for additional processing. It is suitable for sound-activated projects, alarms, and interactive devices.
