Introduction 

Grove - Sound Sensor can detect the sound intensity of the environment. The main component of the module is a simple microphone, which is based on the LM386 amplifier and an electret microphone. This module's output is analog and can be easily sampled and tested by a Seeeduino.

Features
  • Easy to use
  • Provides analog output signal
  • Easily integrates with Logic modules on the input side of Grove circuits
