Claim 0:
1. A sensor device for determining a first and a second angle indicative of an orientation of a magnet having an axis, the sensor device comprising:
a semiconductor substrate comprising a plurality of magnetic sensors configured for determining at least iii) and iv) of the following:
i) a first magnetic field gradient of a first magnetic field component oriented in a first direction parallel to the semiconductor substrate along said first direction; and
ii) a second magnetic field gradient of a second magnetic field component oriented in a second direction parallel to the semiconductor substrate and perpendicular to the first direction, along said second direction; and
iii) a third magnetic field gradient of a third magnetic field component oriented in a third direction perpendicular to the first direction along said first direction; and
iv) a fourth magnetic field gradient of the third magnetic field component oriented in a fourth direction perpendicular to the second direction along said second direction;

a processing circuit configured for:
determining said first angle based on at least the third magnetic field gradient; and
determining said second angle based on at least the fourth magnetic field gradient.
