An Arduino sound sensor based on the power amplifier LM386 and the electret microphone. It can be used to detect whether there's sound (like the sound of clapping, noise, etc) surround or not and output the sound strength of the environment. This sound module provides analog output signal.
Easy project operation: Grove compatible interface
Analog output signal
Wide supply voltage range: 4V-12V
Low quiescent current drain: 4mA
Tiny size: 2.0cm x 2.0cm twig module
Minimum external parts
Based on the power amplifier LM386
The Sound sensor module is a simple microphone compatible with many microcontrollers and SBCs like Arduino and Raspberry Pi. Based on the power amplifier LM386 and the electret microphone, it can be used to detect whether there's sound (like the sound of clapping, noise, etc) surround or not and output the sound strength of the environment. This module can easily integrate with logic modules on the input side of Grove circuits and its output is analog. With its tiny size and high performance, it is perfect for your Raspberry Pi audio detection project and interactive project.

Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfil a variety of needs. Not only are these open hardware, but we also have open-source software.
For all Grove users (especially beginners), we provide you with the guidance of operation. Please read the instructions through the official website before you using the product.
