Descrizione
Questo sensore di suoni realizzato da Sparkfun è particolarmente potente ed efficace: fornisce diversi tipi di output che consentono non solo di rilevare i suoni, ma anche di valutarne l’ampiezza e direttametne anche il loro output.

The Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent.
The envelope output allows you to easily read amplitude of sound by simply measuring the analog voltage. Gain can be adjusted with a through-hole resistor, to change the threshold of the binary (gate) output pin as well. Check the hookup guide below for more information about setting gain.
Each of the three output signals is present on the .1″ header at the edge of the board. They are active simultaneously. If you aren’t using one in your particular application, simply leave that pin disconnected.
