Seismic Digitizer

I seem to remember reading about using an Arduino as a digitizer for a seismometer. Has anyone pursued that endeavor?

Thanks,
Jerry

Thank you for your reply.

I should have explained further. I have a Guralp 40t seismometer but need an analog-to-digital digitizer. I am not referring to just an ADC, but analog signal input (three chanels); some amplification; digital conversion (ADC); and final output to USB.

Asking a lot, right?

All that is covered in the TC1 seismometer link, and links therein. For amplifier and digitizer see https://www.boisestate.edu/eslab/building-a-tc1-system/

Per the Guralp 40T spec sheet, it has something on the order of 150 dB dynamic range which implies a 26 bit (or better) ADC. An ADC that doesn't significantly limit sensor performance is going to be a standalone ADC, not integrated on a microcontroller.

Certainly a run of the mill microcontroller can be involved in the build, but the ADC stuff is the hard part.

Thank you, MrMark. That is what I was afraid of. Many thanks for your reply.

Good point. With a professional, high quality sensor, use an appropriate, professionally designed interface.

There is no point in wasting your time with Arduino.

Tis true! I must have misread previously. THANKS
