KY-030 Microphone Sound Sensor Module
This module is ideally suited to adding sound control to your project. This is a sound detection module which can detect noise and produce an analog output that can be used to trigger a switch like response. This allows you to replace those mechanical switches that have been holding back your project all this time with something a little noisier or begin a long term sound level monitoring system.
An onboard potentiometer allows you to tailor to sensitivity/trigger level to account for a project's background noise. As a simple module it will suit use within a large range of projects based on microcontrollers such as Arduino boards and the Raspberry Pi.
The module has a M3 mounting hole allowing for its easy attachment to a multitude of surfaces.
