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 ...

ABLIC launched the S-5611A linear Hall effect IC for general-use devices. The adoption of natural energy such as solar power ...

[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.

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance. They function via an electrical potential that is developed across ...
