He built this set of no-contact limit switches using a hall effect sensor. The small black package sticking out past the end of the protoboard is the sensor. It is used to detect a magnetic field.

A new smart energy monitoring sensor from Melexis has been introduced that can be used for clamp-on measurement in a range of applications. Dubbed MLX91218-LF, the hall current sensor is designed for ...

That’s the subject of the second video below, which uses a different Hall sensor — an Allegro A1304 — and is mainly concerned with getting the output of a non-motorized but considerably ...

Innovative inverted pyramid Hall-effect sensors offer improved accuracy and reduced crosstalk, paving the way for ...

Delft University's inverted pyramid Hall-effect sensor achieves improved sensitivity and offset reduction, enhancing performance in magnetic sensing technology.
