3 unusual facts about Hall effect sensor


Analog stick

The analog pad used magnet-based Hall effect sensors, which was a unique implementation of the technology that was carried forward into the design of the Dreamcast controller as well.

Flow sensor

Hall effect sensors may also be used, on a flapper valve, or vane, to sense the position of the vane, as displaced by fluid flow.

Turbomolecular pump

Hall effect sensors can be used to sense the rotational position and the other degrees of freedom can be measured capacitively.


Wheelchair trainer

A quadrature rotary encoder or hall effect sensor can be implemented to provide sufficient speed and direction information to enable virtual navigation interface with video games in a manner similar to using a joystick or gaming console.
