Yeah, I'm reading a 2g accelerometer! This is with my Christmas toy, a Raspberry Pi-2. Right now, it's an ADXL345 accelerometer, but I've got some others. Now I have to dip into seismic software, mainly an accelerometer program with integration. I know they are out there. Next step will be to I2C chain a bunch of them together to get the thermal noise down. Should be able to detect the dog sneaking down to her food! :)
ps. stuck on finding good software for real-time plots.
