High Sensitivity Sound Microphone Sensor Detection Module

• The Product  for sound detection module has two outputs: AO, analog output, real-time output voltage signal of the microphone DO, when the sound intensity reaches a certain threshold, the output high and low signal
• There is a mounting screw hole 3mm, the use 5v DC power supply
• With analog output ,there are threshold level output flip
• High sensitive microphone and high sensitivity.
• A power indicator light, the comparator output is light
