I would like to know how it is possible to remove (external) offsets like temperature and unwanted magnetic fields when using a hall sensor. As far as I know this should basically be possible by using several hall sensors and rearrange them in a certain way. I think it is even possible to swap the current and hall connectors but I'm not sure about that. Note: In my documents (which are in a different language) this principle is under the term
spinning current principle
but when I google that it looks way more like a special solid physics effect or so.
