Analog Sound Sensor V2.2 Module - Gravity Series

As weird and wonderful creatures living in audio-filled worlds, with sounds all around us pretty much every waking (and sleeping) hour, we humans are quite good at decoding and interpreting audio, but with our brains doing a lot of behind-the-scenes work at filtering out noise and focusing only on what’s important, we are often actually quite unaware of what’s actually happening, and this becomes very apparent when you start experimenting and playing around with Audio in Electronics. These Analog Sound Sensor V2.2 Modules are Gravity Series modules from DFRobot, and are designed to work with microcontrollers like Arduino to help you experiment with the world of Audio in electronics, and provides electronics with a way to listen to the world, interact with audible signals rather than electronic signals, and enhance functionality with a whole new sense.

While the Analog Sound Sensor V2.2 Module may be relatively basic compared to our brains, simply identifying sound levels rather than distinct frequencies, this module can be awesome for noise-based projects like clap-based lighting or wallet-locators. Furthermore, this module can also be used in other interesting ways when combining it with other handy modules like the Audio Analyser Module, allowing projects to react to specific frequencies when they are loud enough, and sometimes even identify vocal patterns for voice-based due to the high definition analog output. This is all complemented by the onboard Analog Gravity Series interface, making it almost Plug’n’Play with most Arduino Boards and similar microcontrollers, requiring just some simple code and a tiny amount of power to provide its full benefits for your next project. So if you have been planning on improving your lighting, automation or other projects with audio-based controls, or if you’ve other fun ideas on how to integrate audio for even more fun or functionality, the Analog Sound Sensor V2.2 Module is a versatile and cost-effective option for all Makers.
