A Hall effect sensing apparatus for a moving object includes a moving magnetic member having concave and convex segments alternately at is periphery, a detector including a pair of Hall effect elements for converting a magnetic signal to an electric signal, a processing circuit for processing signals from the detector, a magnet for providing magnetic field to the Hall effect elements, and a yoke provided in close proximity to the magnet. The yoke has a smaller surface area than that of the magnet and is movably arranged so as to adjust detecting sensitivity of the sensing apparatus. Therefore, even though there are some variances of magnetic characteristics in the detector, the detecting sensitivity of the sensing apparatus can be adjusted to an optimum level by observing a signal outputted from the processing circuit.
