Arduino Sound Detection Sensor
The Sound Detector
Module is a small board that combines a microphone and some processing
circuitry. It provides not only an audio output, but also a binary
indication of the presence of sound, and an analog representation of
it’s amplitude.
The Module has 2 outputs :
- AO : analog output, real-time
output voltage signal of the microphone.
- DO : when the sound intensity
reaches a certain threshold.
When the sound level exceeds the set point, an LED on the module is
illuminated and the output is sent low.
The
threshold-sensitivity can be adjusted via potentiometer on the sensor.
