description
When logging acceleration data from multiple sensors, I get very high offsets. In the attached image, you can find the absolute gravitational value (sqrt(x^2 + y^2 + z^2)). While 2 of the sensors seem to work fine, violett and yellow have a relative difference of >10%... How can I calibrate the sensors?

Thanks,
Yves!

    Hi yves,
    You can't calibrate the sensors in hardware/firmware. You can do it in software though.

    Cool, nice to know. Because like that the whole setup is not really useful.

    Can you give me the corresponding manual, script or whatever to calibrate them?

    Best wishes,
    Yves
