- alexhill 13y agoThey vary voltage in response to a magnetic field. Among other things they're used to detect current in a wire without interrupting the circuit.

- admsyn 13y agoJust FYI, Hall Effect sensors are pretty actually old school[1], simple sensors. The kind of thing that's easy to play with via an Arduino, for example[2].
