SparkFun Sound Detector SEN-12642
Overview
The SparkFun SEN-12642 is a self-contained sound detector module intended for simple sound-level and event-detection projects. It combines a microphone and on-board signal conditioning so it can be integrated quickly into microcontroller or prototyping projects. The module is designed for straightforward use in hobbyist, educational, and basic monitoring applications.
Why Choose This Part
As a self-contained module, the SEN-12642 removes the need to design a microphone preamp and basic signal conditioning, speeding up prototyping. Its small, breadboard-friendly form factor and simple interface make it easy to connect to microcontrollers or logic inputs for event-driven projects.
Applications
Getting Started
The module connects directly to common microcontroller boards such as Arduino or SparkFun RedBoard; use an analog input or digital input (depending on how the module exposes its output) to read sound events. For quick experiments, mount on a breadboard, wire VCC/GND and the output pin to your board, and use the Arduino IDE or any microcontroller toolchain to read the signal and implement thresholding. Refer to the SparkFun product page for example wiring and code.
