How does the sensor communicate?

Question

Is it through voltage fluctuations?

I can see that there is only one wire as the signal. Is it modulated somehow, or is there a carrier wave?

I wasn't able to find the information in the datasheet linked to the article, but maybe someone can point me in the right direction?

This is from the KEMET catalog and shows the frequency and amplitude range (along side a range of example applications). Ideally, you would sample the sensor at a high rate and perform a FFT to identify the amplitude at different frequencies. I hope that this helps.

It functions similarly to a microphone. The amplitude of the signal is proportional to the strength (or force) of the vibration. The frequency of the signal matches the frequency of the vibration.
