Compass Magnetic Interference

Posted by emir serdar aras on January 26, 2010 at 11:57am
Hey guys,
I try to search the ways of solutions to the magnetic interference of compass to read correct datas from compass for my project in uni. Do you have any experiment or suggestion for that problem except taking the compass more far away from the magnetic material

    Distance and use those steel (or metal) braid sleeve over twisted wires.

    I had many issues with this especially since I had limited fuselage area and my magnetometers were placed near the high current wires feeding the electric motor. If your magnetic source is the electric current through wires, you can have a twisted pair arrangement where you braid the upstream and downstream current wires to cancel as much of the magnetic field as possible.

    Oh and for me, distance was the key.

    emir,

    The Parallax HMC6352 two axis compass module has stray magnetic field protection. Check it out:
