Feature
Main chip:LM393. Signal is clean, waveform is good, driving ability is strong.Build in potentiometer can be used to adjust the threshold level.
When sound intensity exceed a certain threshold, produces low(Digital output 0) signal and light will be off, Otherwise output high(Digital output 1) signal and light will be bright.
Applications: a variety of platforms including Arduino / AVR / ARM/PIC.
There is a mounting screw hole, convenient fixed.
