The KY-037 Sound Sensor Module is a versatile module designed to detect sound intensity and provide corresponding output signals. It features four pins, with two dedicated to power supply.
Pin 1 serves as the analog output, delivering a voltage value proportional to the intensity of the received sound. This analog output can be connected to the analog pins of an Arduino or other microcontroller boards for further processing and analysis of sound data.
Pin 4 functions as the digital output and operates as a switch that is activated when the sound intensity exceeds a predetermined threshold. This digital output can be connected to digital pins on an Arduino or other microcontroller boards to trigger specific actions or responses based on sound detection.
The sensitivity threshold of the sound sensor module can be adjusted using the potentiometer located on the sensor itself. This allows users to fine-tune the module's sensitivity according to their specific requirements or environmental conditions.
With its compact size and straightforward pin configuration, the KY-037 Sound Sensor Module is suitable for various applications such as sound-activated systems, noise monitoring, and audio-responsive projects. It provides a convenient and reliable solution for incorporating sound sensing capabilities into electronic projects.
