Microphone Sensor AVR PIC High Sensitivity Sound Detection Module For Arduino
Module features:
  1. There is a 3mm mounting screw hole
  2. Uses a 5v DC power supply
  3. With analog output
  4. There is a threshold level output flip


  The 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 is a high and low signal
  5. High-sensitivity microphone and high sensitivity.
  6. A power indicator light
  7. The comparator output is light
