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 ...

The idea of this device was to map magnetic field ... magnetic sensor, [Peter] is building a two-dimensional array of magnetic sensors. Basically, it’s just a 12×12 grid of Hall effect sensors ...

"However, this effect always remains in a low level ... Subsequently, they developed a novel anomalous Hall sensor, achieving a low-frequency magnetic field detection capability of 23 nT/Hz 0.5 @1Hz ...

Researchers have developed a 3-axis Hall-effect magnetic sensor based on a compact inverted pyramid structure, offering improved accuracy and reduced signal interference in magnetic field detection.
