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
