    This sound sensor uses the onboard electret microphone as well as the LM386 amplifier to detect any sound that is beyond the threshold setting. The level of the threshold can be set by the on-board potentiometer. This module will output a HIGH signal when the sound is lower than the threshold, as well as LOW when the sound is higher than the threshold.
