Well, let us take a quick look at one of them… According to the datasheet, SS49E is a linear hall-effect sensor that is operated ... an output voltage less than 0.4V will be counted as a sensor ...

As the banana’s magnet gets closer to the electromagnet, the hall effect sensor’s output voltage goes down. Once it drops below a certain threshold, a control circuit cuts power to the ...

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 ...

Allegro MicroSystems, LLC introduces a new Hall-effect speed and direction sensor IC with hysteresis ... A built-in voltage regulator, short-circuit protected outputs, internal Zener clamps ...
