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.

  • \$\begingroup\$ Well, what are these being used for? Offsets for what? \$\endgroup\$

  • \$\begingroup\$ depends on the application but mainly to measure a magnetic field. Or to measure a current? Offsets might occur due to temperature or magnetic influences and so on which are not wanted to be taken into account. \$\endgroup\$

    \$\begingroup\$ Oh, so just offests in the sensors themselves. I think you can do that just by placing one beside or underneath the other facing in the opposite direction, much like how you periodically turn a gyrocompass upside down. But these are for internal offsets. External offsets are something else altogether. \$\endgroup\$
