1. A hall effect sensor (10) for recording the direction of a magnetic field (B), the Hall effect sensor (10) comprising:
a plurality of Hall effect sensor elements (10a, 10b) arranged in pairs (22a, 22b, 22c, 22d), wherein each pair comprises a first Hall effect sensor element (10a) and a second Hall effect sensor element (10b) which are arranged parallel to one another; wherein the Hall effect sensor (10) has a first switch (34) for disconnecting the first Hall effect sensor element (10a) from a power supply (24), and wherein, during a normal operation, the direction of a magnetic field (B), to which the Hall effect sensor (10) is exposed, is ascertained from Hall voltages (Ua, Ub, Uc, Ud) at the pairs (22a, 22b, 22c, 22d) which in each case represent the sum of the individual Hall voltages of the Hall sensor elements (10a, 10b). |
