Sound Microphone Sensor Detection Module for arduino ky-037

For sound detection

Module has two outputs:

1, AO, analog output, real-time output voltage signal of the microphone

2, DO, when the sound intensity reaches a certain threshold, the output high and low signal [threshold – sensitivity can be adjusted via potentiometer]

Module features:

2, there is a mounting screw hole 3mm

3, the use 5v DC power supply

4, with analog output

5, there are threshold level output flip

6, high sensitive microphone and high sensitivity.

7, a power indicator light

8, the comparator output is light
