Microphone Sensor – Sound Detection Module for Arduino

Microphone Sensor – Sound Detection Module for Arduino

• The module has two outputs: AO, analog output,
• real-time output of the microphone voltage signal / DO,
• when the sound intensity reaches a threshold,
• the output high and low signal threshold – Sensitivity potentiometer adjustment
• Application:Microphone sound detection
• use the DC 5V power supply;
• with power indicator

——————–

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
Module features:
1. There is a mounting screw hole 3mm
2. The use 5v DC power supply
3. With analog output
4. There are threshold level output flip
5. High sensitive microphone and high sensitivity.
6. A power indicator light
7. The comparator output is light
