Sound Level Measurement

Using sound sensor we detect ambient sound. This board along with the microphone, has a small built-in amplifier (integrated circuit LM386), because only the microphone would not be able to send signal to Arduino. The connection scheme is very clean, composed of only 3 pins: Vcc, GND and S (signal). In the middle of the plate, there is a potentiometer for sensitivity adjustment.
