Hall sensor main characteristic parameters are the following types.
(1) Input resistance R
(2) Output resistance R
It also changes with temperature changes. Selecting the appropriate load resistance is easy to match, which minimizes temperature-induced drift in the hydrodynamic potential.
(3) Maximum excitation current I - Hall sensor parameters
(4) Sensitivity K
Sensitivity KH=EH/IB, its value is about 10MV (MA.T).
(5) Maximum Magnetic Intensity BM---Hall Sensor Parameters
When the magnetic induction intensity exceeds BM, the nonlinear error of the Hall sensor potential will increase significantly, and the Tesla(T) becomes several thousand Gauss (Gs) (1Gs=104T).
(6) Equal potentials
At rated excitation current F, when the applied magnetic field is zero, it is an error due to the asymmetry of the geometry of the 4 positive poles.
(7) Hall sensor temperature ratio
