Sensor recommendations for seismograph?

Post by guitarist »

I have some strange tremors that occur periodically in my house, and I would like to triangulate it using several homebuilt seismographs. Afterwards, I also plan to use them for actual earthquake detection.

I've got a variety of devices I can built these from--several flavors of Arduino, some Raspberry Pis, even a Beaglebone Black. I don't really care which platform they're built on, just looking for the easiest way to do it. Research on the internet suggests using some accelerometers in the 1-2G sensitivity range, but I've not programmed an accelerometer before, nor do I have a good feel on what I should look out for in an accelerometer. Suggestions?

We have a couple of accelerometers that have a +/-2G range:

We have tutorials for both of these, complete with sample code:
