Abstract
A sensor is provided with a magnetic detection element that can output an output voltage within a predetermined voltage range according to a magnetic field intensity, an output voltage fixing part that can fix a voltage value of the output voltage to a voltage value outside the voltage range, and a drive voltage output part that can output a drive voltage for driving the output voltage fixing part. The drive voltage fixing part outputs the drive voltage to the output voltage fixing part when the ambient temperature of the drive voltage output part exceeds a predetermined threshold, and when triggered by input of the drive voltage, the output voltage fixing part fixes the voltage value of the output voltage to a voltage value outside the voltage range.
