<P>PROBLEM TO BE SOLVED: To provide a sensor device capable of improving accuracy of a correction value as compared with the conventional one. <P>SOLUTION: A sensor device 72 for performing detection by using a non-object signal different from a detection object and outputting an object signal to be the detection object, comprises: effective/ineffective switching means 72a for switching between an effective side to enable an inputted non-object signal and an ineffective side to disable the non-object signal; correction value setting means 72e,72k for performing detection in a state of being switched to the ineffective side by the effective/ineffective switching means 72a and setting a numerical value, obtained as the object signal, as a correction value; and signal correction means 72f,72n for performing detection in a state of being switched to the effective side by the effective/ineffective switching means 72a and outputting a corrected object signal corrected with a correction value set to the object signal by the correction value setting means 72e,72k. Since the correction value to be set is constant regardless of the state of a detection object, accuracy of the correction value can be improved as compared with the conventional one. <P>COPYRIGHT: (C)2012,JPO&INPIT |
