Grove - Sound Sensor

The Sound sensor module is a simple microphone. Based on the power amplifier LM358 and an electret microphone, it can be used to detect the sound strength of the environment. The value of output can be adjusted by the potentiometer. 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.

For all Grove users (especially beginners), we provide you with guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product.

Ready to use with microcontrollers as a digital input. This product also has a compact modular design Plug-and-play grove compatible interface.

Based on the picture above, the grove shield for Arduino is stacked with Seeeduino V4.2. Of course, you can use that shield with an Arduino board too :)

You can get grove HAT for Raspberry Pi here. It may not be the same as the product above but still can use with Raspberry Pi. 

Note: Controllers are sold separately.
