High Sensitivity Sound Microphone Sensor Detection Module For AVR PIC KY-037

High Sensitivity Sound Microphone Sensor Detection Module For AVR PIC KY-037

Description:

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

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
