    BMM150 Bias error

    Hi,

    I would like some clarification about the use of BMM150 magnetometer. I would like to kwow after installation, if there is a deviation of the measure of the magnetic field ? or the error remains constant ?

    My question is to know if new calibrations are necessary after installation and if yes, how to know the frequency of the calibrations ?

    Hi,

    Thanks for your inquiry.

    You don't need to calibrate BMM150 after you solder it on your PCB. You need to run self-test to see if BMM150 is working or not after PCB assembly. You may also need to check if  BMM150 x/y/z data is not saturated on your PCB meaning that you don't have other strong inductor or metal screws near BMM150.

    Every time when you start using BMM150 in your application you always need to calibrate it because the environmental magnetic filed has changed. Please refer to online article at https://www.ednasia.com/sensor-data-fusion-enhancing-gaming-navigation-and-vr-experiences/ for more information.

    Thanks.
