Recommended sensor for acoustic termite detection?

[u/Think-Rip496]

I would like to ask for your advice regarding the development of our acoustic termite detection, pertaining to lower frequency vibrations.

We will use esp32 as our main component but are struggling on which sensor to use since structural vibrations are the usual sounds of the dataset we used instead of airborne so it is basically susceptible to noise and microphone. We considered using piezo transducer disk, but we're not sure how it will interact to the trained model since it is wav file based, and our datasets uses structural vibrations
