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
