What is the magnetic rms noise of the LSM9DS1? I can not find it or something simular in the datasheet. Thanks for your help.

Magnetometer part of LSM9DS1 is basically the same as LIS3MDL.

Thanks for your answer. These sensors have zero gauss levels of +/- 1 gaus which is a quater of full scale. Is that correct ? Why not all of your sensors have that offset compensation to reduce the zero gauss level.

Yes, it is correct.

In the final application, there is always some hard iron distortion caused by surounding objects which need s to be compenstated. The zero gauss level will be compensated together with the HI distortion, so it is not a big problem.
