Getting Vibration data from MMC

I have been using MMC and its accelerometer to detect the vibration for the application I am developing.
I calculated the magnitude using the xyz gforce vectors. But even if I am not moving the MMC it is still giving me this output:

I think it is residual magnetism or gravity affecting the calculation. Is there a way to adjust the boundary of the accelerometer?


  • Hi @Alliah
    It could be a number of things like surrounding magnets and such.
    What you can do is tare the data in software.
