This
is a multipurpose sound sensor which can be used to sense sound and
audio. The sensor provides a digital output when the measured sound
increases beyond a set threshold. 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 directly connected to an Arduino,
Raspberry Pi, AVR, PIC, 8051 or any other microcontroller to read the
sensor output.
