- Small and easy to use audio sensing board with 3 different outputs
- Provides binary indication of sound and analog representation of amplitude
- 1.2MHz gain bandwidth
- RoHS compliant
The Sound Detector - LMV324 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. 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.
