Description:
The sound sensor module has a built-in capacitive electret microphone which is highly sensitive to sound. Sound waves cause the thin film of the electret to vibrate and then the capacitance changes, thus producing the corresponding changed voltage., so it can detect the sound intensity in ambient environment. You can adjust the sensitivity with by adjusting the Potentiometer.
