1. A wheel speed sensor for a vehicle, comprising:
a base unit having upper and lower surfaces respectively facing in different directions;
a plurality of chip units disposed over the upper surface of the base, each chip unit configured to measure a magnetic field component of a measurement target moving below the lower surface of the base unit; and
a plurality of support units protruding upwardly from the upper surface of the base unit and respectively configured to hold the plurality of chip units at elevated positions from the upper surface of the base unit,
wherein each chip unit has a different height, different depth, different mounting direction or different angle with respect to the measurement target such that the magnetic field component of the measurement target measured by each chip unit has a different value.
