It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Getting a magnetic field to balance on another magnetic ... he got off of Taobao (the Chinese version of eBay), a hall effect sensor, and a handful of current regulation ICs.

Thanks to its magnetic-field detection in X, Y, and Z directions, Diodes Inc.’s automotive-qualified AH4930Q is able to ...

Subsequently, they developed a novel anomalous Hall sensor, achieving a low-frequency magnetic field detection capability of 23 nT/Hz 0.5 @1Hz and a Hall sensitivity of 7028 μΩcm/T, which are 3 times ...
