A Grove module for detecting and filtering your sound environment

This Grove compatible module is a sound sensor with an LM2904 amplifier and an amplified electret microphone. The detected sound is filtered twice to remove any unwanted noise. Depending on the input signal, it produces an analogue output signal with a value between 0 and 1023.

You can connect this sensor using a Base Shield or Mega Shield to an Arduino, Raspberry Pi or any other system of your choice.
