The SparkFun 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, so you can use as many or as few as you want at once.<\/p>\n\n
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.<\/p>\n\n
Each of the three output signals is present on the .1\" pin-out at the edge of the board. They are active simultaneously. If you aren\u2019t using one in your particular application, simply leave that pin disconnected.<\/p>\n\n
