High Sensitivity Microphone Sensor
The module has two outputs:
AO, analogue output, a real-time output voltage signal of the microphone
DO, when the sound intensity reaches a certain threshold, the output high and low signal [threshold – sensitivity can be adjusted via potentiometer]
Module features:
3mm mounting screw holes
Use 5v DC power supply
