Abstract
A sensor for measuring a rotation speed of a magnetic encoder includes a first magnetic detector detecting a magnetic field induced from the magnetic encoder and outputting a strength value of the magnetic field as a first electrical signal, a second magnetic detector detecting the magnetic field induced from the magnetic encoder and outputting a strength value of the magnetic field as a second electrical signal, a first output signal generator for generating and outputting first rotation data including information indicating a rotation speed of a wheel based on the first electrical signal, and a second output signal generator configured to generate second rotation data including information indicating a rotation speed of the wheel based on the second electrical signal. The information indicating the rotation speed in the second rotation data may have a higher resolution than the information indicating the rotation speed in the first rotation data.
