PROBLEM TO BE SOLVED: To provide a sensor device which enables miniaturization, and to provide a control system equipped with the device. SOLUTION: A first sensor device 6 includes a sensor section and a signal superimposing separating circuit which transmits detection information detected from the sensor section to the outside. The first sensor device 6 includes a connector to which a direct current supply line Wdlc is connected, and is driven by receiving a supply of direct current power via the direct current supply line Wdlc. The signal-superimposing separation circuit superimposes the detected information and the power and transmits them as a direct current superimposed signal to the outside via the direct-current supply line Wdlc.
