Description

The VCC external 5V voltage, GND with an external GND, DO small board analog output interface.
Comparator chip LM393 ,it is stable.
single channel signal output, the output effective signal is low level.
when there is sound,outputs low level and the signal light.
can be used for Acoustic control light , give sound and light A-larm working with Photosensitive sensor ,and sound control,sound detect.
