Did anyone ever replace the mic with a structure-borne sound sensor?
Hi
I would like to record the activity of wood boring insects and therefore use a structure-borne sound sensor. Can anyone recommend how to implement this on a AudioMoth? Can I use the rx pin and make this an input for sound or better replacing the mic? And can anyone give me a guideline how to pick a sensor that works well with the e rest of the electronics?
Anyway, I want wo say “Thank You!” for this cool tool!
Cheers
Jonas

How much power you take from the 3V output will depend a little on the SD card. The regulators are rated to 100mA so to avoid any affect on audio quality you should ensure that the SD card write current, plus whatever you use from the GPIO, is less than that total. For the input amplitude, it should basically just look as much as possible like the output of the equivalent electret microphone - probably around 5mV RMS.
