Hi, I should need to know the Accuracy for the acceleration ang angular velocity measurement of the LSM9DS1 Thank you in advance, Bests, Nico

Hi @NTacc.1022​ , in the accelerometer case, the accuracy is basically related to the minimum detectable acceleration signal, to the noise and to the Linear acceleration typical zero-g level offset accuracy: the maximum of these values is ±90mg, from datasheet. Similarly for the gyroscope, the Angular rate typical zero-rate level determines the overall accuracy and is ±30dps in the 2000dps case. Btw, please note that in case you need to calculate the space from the acceleration and the angular velocity, you have to take into account both offset drift (that have to be compensated step by step) and noise inaccuracy, that can be reduced by sqrt(N) from signal theory averaging multiple acquisitions.
