Application

Due to lack of information we hooked one up here at dipmicro.

It is a microphone with high sensitivity amplifier. There is no flip-flop nor delay circuit, so sound comes out amplified and clipped and it will be up to connected CPU to decide what to do with it. Basic processing could be done by measuring pulse widths and signal duration.

Trimpot regulates offset for opamp, so there is point where it changes between active low and active high. The red LED is on when active low and off when active high and flickers when sound is detected.
