Abstract
A sensor device wherein when a first sensor detects a detection object, the first sensor changes its output voltage level, and when the processor unit detects the change of the output voltage level of the first sensor as an interrupt signal, the drive voltage level of the first sensor is switched from the first signal level to the second signal level which is different from the first signal level and the drive voltage level of the second sensor is switched from the second signal level to the first signal level which is different from the second signal level.
