Abstract

A sensor device for determining an orientation (α,β,ϕ,ψ) of a magnet (701) that is pivotable about a reference point (Pref), the sensor device comprising a semiconductor substrate (703) comprising a first and a second magnetic sensor (51, 52) spaced apart in a first direction (X), each configured for measuring a first magnetic field component (Bx1, Bx2) oriented in the first direction (X), and a second magnetic field component (By1, By2) oriented in a second direction (Y); wherein the sensor device further comprises a processing circuit configured for determining: i) a first magnetic field gradient (dBx/dx); ii) a second magnetic field gradient (dBy/dx); iii) a first angle (α,ψ) based on the first magnetic field gradient (dBx/dx); iv) a second angle (β,ϕ) based on the second magnetic field gradient (dBy/dx). A sensor system comprising said sensor device and said magnet.
