Abstract
A method for determining of a position of an object using a sensor arrangement that includes a first magnetoresistive element and a second magnetoresistive element. A source provides a magnetic field with first and second magnetic poles. The source is arranged between the first magnetoresistive element and the second magnetoresistive element with the first magnetic pole facing the first magnetoresistive element and the second magnetic pole facing the second magnetoresistive element. The first magnetoresistive element is arranged in the magnetic field and provides a first output signal dependent on a position of the first magnetoresistive element relative to the magnetic field source. The second magnetoresistive element is arranged in the magnetic field and provides a second output signal dependent on a position of the second magnetoresistive element relative to the magnetic field source. A measurement unit determines a position of the magnetic field source relative to the first and the second magnetoresistive elements dependent on the first output signal and the second output signal.
