Sound Sensor Module

This sound sensor can identify the presence of sound. The sensor sensitivity can be adjusted by potentiometer. The sound sensor module work like that: when the intensity of the sound can not reach set threshold, the OUT pin will output high level 5 volt ( open ). When the intensity of the sound reach more than the set threshold, the OUT pin will output low level (2.5 volt). supply voltage range: 3.3V - 5.3V Comparator IC: LM393 Mic type : capacitive Output: Analog ( normally open) - change from 5 volt to 2.5 volt when detect sound. Size: 39 x 17 x 10 mm
