I have an MCU with an accelerometer, tightly mounted onto an AC motor inside a production hall.
Once an hour, it collects 1 sec. (Sample rate is 5000) of acceleration data for the motor and saves it.
When I try to display this data, I get these weird spikes:
Can somebody tell me, what these spikes/artifacts could be?
I'm sure my import/chart setup is correct, so I'm pretty sure it's an issue with my components.
Extra info: The components are located inside a plastic box that's mounted with a metal backplate. Everything should be electrically isolated from the AC motor. When testing in office environment (On a test motor), these spikes did not occur.
EDIT: I come from software - I'm pretty new to hardware and electronics, so bear with me, thanks! :-)
