The high sensitivity sound detection module is an analog/digital sensor that uses a condenser microphone to observe changes in environment noise. Generally used to detect sound above certain levels. It has a potentiometer to set the noise detection threshold.
The digital output provides a HIGH signal when sound above the threshold is detected. The analog output shows values representing the noise levels detected by the condenser microphone, the values are relative to the provided voltage and potentiometer position, making it difficult to reconstruct the audio from the obtained values.
This module is compatible with popular microcontroller platforms like
Arduino, ESP32, ESP8266, and Raspberry Pi.
