The Sound sensor module is a simple microphone. Based on the power amplifier LM386 and the 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.
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 Arduino board too :)
You can get grove HAT for Raspberry Pi here. It may not be the same as product above but still can use with Raspberry Pi.
Note: Controllers are sold separately.
