SHILLEHTEK KY-037 Sound Sensor Module

Features: 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.
