The Sound Sensor Module detects a sound nearby through its on board electret microphone. It also has a comparator circuit which gives a HIGH (5V) or LOW (0V) signal. This only needs 3 pin. Supply Voltage (+5V), GND, and the digital OUTPUT which gives a HIGH or LOW signal when a sound is detected or not deteced. The sound amplitude threshold/compare can be adjusted thru the on-board potentiometer so you can set the loudness to detect.
