DIY Hall effect sensors

[Shein]

I have a set of rudder pedals I’m reworking. I have potentiometers hooked up to an arduino board but apparently hall effect sensors are better. I can find tons of tutorials on how to use them to detect the presence of a magnet but not how to have it be output as an analogue axis. Has anyone done it? Have links to videos or articles? Thanks

Hi, I made a simple Hall-sensor-Poti some years ago. It was a replacement in an old CH-Flight yoke.

The used Hall-sensor (A1302 or SS49E) detect the rotation of the north-south axle (see the magnet).

You can usefully detect only 120° of rotation, because it flips after 180°.

0°-30° and 150°-180° deliver unusable small values.

Hi.

First of all, make sure the type of Hall eff sensor is the correct one (see @yogi149 above). The legs should be conected as the ones out of a pot; one for positive, the other one for ground end the third one as the signal.

Then make sure the magnet is placed corretly relative to the  sensor (90º from the N-S axis to the flat spot or upper position of the sensor).

Could you please share the STL files for those?
