Abstract
An apparatus for sensing a rotating body includes a detection target arranged on a surface perpendicular to an extension direction of a rotating shaft of the rotating body, a sensor module facing the detection target, and comprising two sensors disposed in a rotation direction of the rotating body, and a rotation information calculator configured to calculate rotation information of the rotating body based on sensed values from the two sensors, wherein the rotation information calculator is further configured to calculate a rotation angle of the rotating body in accordance with a difference value generated from the sensed values.
