@misterlisty that’s about as vague as it gets...
I recommend you start by reading the accelerometer’s datasheet to learn of its capabilities.
An accelerometer detects just that: acceleration, and you can sample the acceleration values at regular intervals to try to detect all sorts of things. I believe you can even “stream” the values samples by the accelerometer. But high frequency vibrations for instance may be an issue as they may exceed the capabilities of the accelerometer. High sampling rates may also be an issue if you have lots of computations to perform.
It’s really difficult to help you much further without any indication of what exactly you are trying to measure / detect, and what the threshold are.
