OdiySurveil(TM) 10pcs 40 Pin 2.54mm Straight Single Row Pin Header Strip

Product Review

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.

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 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.

VCC: 3.5V to 5.5V. Ideal voltage is 5V.

Three independent outputs: The SparkFun Sound Detector provides three outputs—audio, binary sound detection, and analog amplitude—allowing you to use any combination of them simultaneously
Envelope output for amplitude measurement: Easily read the amplitude of sound by measuring the analog voltage from the envelope output pin
Adjustable gain: Gain can be modified using a through-hole resistor, which also adjusts the threshold for the binary (gate) output pin
Simple pin-out connection: The three output signals are accessible on a .1" pin-out at the edge of the board and are active simultaneously
Flexibility in usage: If a particular output is not needed, simply leave the corresponding pin disconnected while still using the others
