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
