1. A sensor system comprising:
a first pair of sensors configured to detect a first magnetic flux density differential of a rotating target at a first point in time;
a second pair of sensors configured to detect a second magnetic flux density differential of the rotating target at a second point in time after the first point in time; and
a controller configured to determine that a second value of the second magnetic flux density differential of the rotating target is equivalent to a first value of the first magnetic flux density differential of the rotating target and output a pulse corresponding to a degree of rotation of the rotating target in response to determining the second value of the second magnetic flux density differential of the rotating target is equivalent to the first value of the first magnetic flux density differential of the rotating target.
