Features:
1. A mounting screw hole 3mm
2. The use of 5v DC power supply
3. With analog output
4. There are threshold level output flip
5. The high sensitive microphone and high sensitivity.
6. A power indicator light
7. The comparator output is light
8. 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
