PROBLEM TO BE SOLVED: To provide a sensor device having the function of automatically regulating gain and/or offset in an analog output circuit. SOLUTION: The sensor device includes a detecting section for detecting change of a detection object, an analog output circuit for amplifying an output of the detector and output it to the outside, and a regulating means for setting the gain and offset of the analog output circuit. The sensor device also includes an arithmetic means that receives a trigger signal input especially when the detection object is in a predetermined state, and operates, and detects an output value of the detecting section or the analog output circuit (monitor means), and calculates the gain and/or offset required to match the output of the analog output circuit with a predetermined output specification based on the detected output value.
