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 ...

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 by the magnetic ... built a bit fancy pocket throttle tester using an ...

This sensor sits in line with the water line and contains a pinwheel sensor to measure how much water has moved through it. There is an integrated magnetic Hall-Effect sensor that ... suitable ...

[John Crombie] had a crack at building one using linear Hall effect sensors and magnets as the ... [John] utilises the Arduino pro micro for its copious analog inputs and USB functionality.

Would you believe it, the ESP32 popular Wi-Fi and Bluetooth chip has a built-in Hall effect sensor. Espressif Systems makes the ... For more information, the Arduino community seems to have ...
