This sound detector board uses an electret microphone and inputs an amplified audio signal from that microphone into an LM393. The output sent from that LM393 is a digital on/off square wave representing the pulse widths of the input audio signal. The on-board trimpot allows for calibrating how sensitive the sensor is to loud vs quiet sounds.
