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

Description

The module has two outputs:
AO, analog output, real-time output of microphone voltage signal
DO, when the sound intensity reaches a certain threshold, the output of high and low level signals, [threshold-sensitivity can be adjusted by potentiometer]
Description
Size:32mm*17mm*8mm(length*width*height)
Main chip:LM393, Electret condenser microphone
Working voltage: DC 4-6V
Signal output indication
Single channel signal output
The output effective signal is low level
When there is sound, outputs low level and signal light
Can be used for Acoustic control light , give sound and light alarm working with Photosensitive sensor ,and sound control, sound detect
Circuit board output switch quantity
Note: The Maximum induction distance is 0.5M
Features
Uses 5V DC power supply
