Grove – Sound Sensor
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.
