FEATURES:
 
A condenser microphone is used by the analog/digital KY-037 high sensitivity sound detection module to detect changes in ambient noise. used to identify sound levels exceeding a given threshold. The noise detection threshold can be adjusted using a potentiometer.

When sound is detected above the threshold, a HIGH signal is sent by the digital output. It is challenging to reconstruct the audio from the values obtained since the analog output displays values that indicate the noise levels detected by the condenser microphone and are dependent on the supplied voltage and potentiometer position.


Popular microcontroller platforms like as Arduino, ESP32, ESP8266, and Raspberry Pi are compatible with this module.
