The Hall effect sensor shouldn't be vulnerable to orientation like an accelerometer would be.<br /><br />I did find (accidentally) an Android compass app that gives the strength of the magnetic field, in microTesla. It seemed to be at least plausibly accurate - certainly qualitatively better than my B field sensor was when I tested it.Tatnall Physicshttps://www.blogger.com/profile/09436753600662471697noreply@blogger.comtag:blogger.com,1999:blog-6550984149903805046.post-69101616305892292252015-02-07T08:13:19.859-05:002015-02-07T08:13:19.859-05:00I always get frustrated with physical compasses be...I always get frustrated with physical compasses because they really only measure the direction of the field in the horizontal plane. Way up here in MN, for example, the earth's fields has a huge vertical component. Do phones help with that?Andy Rundquisthttp://arundquist.wordpress.comnoreply@blogger.com
