In general, can you swap in a piezo element in place of a condenser microphone?
For example this pizeo: https://www.digikey.com/product-detail/en/0/490-7713-ND
into this circuit board: https://www.banggood.com/10Pcs-Micr...ection-Module-p-1254927.html?cur_warehouse=CN
I'm trying to monitor water flow (simple on/off, not rate) in a copper water pipe. I thought this audio detection circuit board would work. I'm thinking a piezo element, mounted to the pipe, might work better.
When I say "doesn't work", I mean that even when zip tied tight to the copper water pipe, it does not get triggered by the sound of the water. The sensor itself does work, I can trigger it by tapping on it, speaking loudly, or clapping.
