PROBLEM TO BE SOLVED: To provide a Hall sensor consuming less power and having reduced noise characteristics, capable of measuring a magnetic field difference between at least two different locations.SOLUTION: The Hall sensor comprises: at least four sensor terminals (EXT_A, EXT_B, EXT_C, EXT_D) for connecting a Hall sensor HS; and at least two Hall sensor elements interconnected by a two or higher dimensional mesh. The two Hall sensor elements are basically distributed to two equally divided portions (B, B) equally, and connected so as to electrically generate a difference value between two of the sensor terminals. The Hall sensor elements of the two portions (B, B) are respectively interconnected with each other on the first and second portions of the mesh. Each sensor value of the one portion Band each sensor value of the other portion Bcancel each other out when a uniform magnetic field of the same intensity and in the same direction is applied.SELECTED DRAWING: Figure 1 |
