This is a High Sensitivity Microphone Module for Arduino, AVR and other Microcontroller units.

For sound detection module has two outputs:
1. AO, i.e. 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

Features:

• there is a mounting screw hole 3mm
• the use 5v DC power supply
• with analog output
• there are threshold level output flip
• Highly sensitive microphone and high sensitivity.
• A power indicator light
• The comparator output is light
