ELECFREAKS Octopus Analog Noise Sensor

Octopus Analog Noise Sound Sensor Detection Module is a sensor module based on the MIC sound sensing elements. The sound Sensor is particularly sensitive to sound intensity, and it can be used to detect ambient sound levels. Louder noise brings bigger output Sine wave amplitude.
