8.3 What to Do and What Not to Do

The Hall element is sensitive to magnetic fields that are perpendicular to the top of the package. Therefore, to correctly detect the magnetic field, make sure to use the correct magnet orientation for the sensor. Figure 25 shows correct and incorrect orientation.
