Crowtail - Sound Sensor 2.0

Crowtail - Sound Sensor 2.0 can detect the sound loudness of the environment. The main component of the module is a simple microphone to receive the sound signal, with band pass filter and a LMV358 amplifier to make the output signal easy to be received by microprocessor.

This module outputs analog signal that shows the relative loudness. Besides, an on-board potentiometer can be used to adjust output voltage.
