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 ...

Twisting the hall sensor throttle simply varies the strength and polarity of the magnetic field next to the integrated ... But for demo purposes I built a bit fancy pocket throttle tester using an ...

Using an Arduino, a Hall effect sensor and an electromagnet ... the permanent magnet and uses that information to modulate the magnetic field of the electromagnet, with everything being crunched ...

There is an integrated magnetic Hall-Effect sensor that outputs an electrical pulse ... This is used to read the output pulses coming from the water flow sensor. When Arduino detects the pulse, it ...

While most sensors ... Hall effect. However, it doesn’t end there. In the Hall effect, when a conductor or semiconductor with current flowing in one direction is introduced perpendicular to a ...

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 ...

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.
