The Hall sensor is divided into two types: linear type and Output Switch Type Hall Sensor. The output characteristics of the two types of Hall are different. The function of each output pin should be distinguished during detection.

The switch type is equivalent to the level inversion when the value is set to GS; the Linear Hall Sensor may be that the voltage gradually changes, and when it is constant, the post-processing circuit outputs an inverted level. It is generally recommended to use linear, switch type often causes the set value to drift due to temperature and other reasons, resulting in reduced sensitivity.
