Hall Effect Sensor Raspberry Pi

I tried dozens of different hall effect sensors to see which one would work best for the spokepov kit to determine the wheel location and this one came out on top. I wanted a cheap compact magnet that i would be able to easily mount on the printer so i ordered some from. It cost approximately 1 from cpc.
