About this item

[Sound Detection]: The module has a built-in microphone that detects sound waves in the surrounding environment. When sound waves reach the microphone, they cause changes in air pressure.
[Plug-and-Play Compatibility]: KY-037 is compatible with common development boards and microcontrollers, offering a plug-and-play solution for users with varying levels of technical expertise.
[Versatile Applications]: Suitable for a wide range of applications, including sound-activated electronic projects, voice recognition systems, and interactive sound installations.
[Analog Signal Generation]: The microphone converts these changes in air pressure into analog electrical signals. The strength of the electrical signal corresponds to the intensity of the sound.

Sensitivity could not be decreased enough to get a reading digital read of 0, even in an absolutely silent room. Pins on the microphone were twisted when received to the point both were in contact. Untangling them caused them to break.
