Abstract
A controller for a Hall effect sensor includes a sensor section including a Hall effect sensor with a hysteresis set in the output electric signal characteristic with respect to the magnetic flux density, a power supply section for supplying a source power to the Hall effect sensor, and a signal processor for processing a signal output from the sensor section. The power supply section supplies power with a voltage, which is varied cyclically in a predetermined range and is increased gradually, to the Hall effect sensor.
