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.

For all Grove users (especially beginners), we provide you 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 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.

Hi, may I ask is this Grove sound sensor can be able to connect to Arduino UNO and control it via Arduino IDE using Arduino codes?

Hi, is this sensor can differentiate the level of frequency (dB)?
( Amydiamni, 20/04/2020 )
Hi, it can only be used to detect sound. Thanks :)
Hi, does this sensor detect only input sound or still able to detect surrounding sound even if not input the sound? ( Niresha, 13/04/2020 )
Hi, it can detect sound only. Thanks :)
How many maximum output value of grove sound sensor?
How to convert output value to dB?
( Audchara , 30/03/2020 )
Hi, this sensor did not use for sound measurement, more like for application with  sound-activated sensor. For more info, you may refer to this. Thanks :)
