DESCRIPTION
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 analogue representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once.
The envelope output allows you to easily read the amplitude of sound by simply measuring the analogue 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.
