This is a multipurpose sound sensor which can be used to sense sound and audio. The sensor provides a digital ouput when the measured sound increases beyond a set threhold. This threshold level can be adjusted using an onboard potentiometer. The sensor outputs a logic one(+5V) at the digital output when it detects sound and a logic zero(0V), when there is no sound detected. An onboard LED is used to indicate the output status. This digital output can be directely connected to an Arduino, Raspberry Pi, AVR, PIC, 8051 or any other microcontroller to read the sensor output.
The onboard potentiometer can be used to set the sound threshold. To set the potentiometer, use a screw driver and turn the potentiometer knob.
