<p>PROBLEM TO BE SOLVED: To provide a sensor device which can suppress an error due to temperature of a liquid.SOLUTION: A sensor device includes electrode pairs 33, 38, and 60. The electrode pair 60 is covered by an insulating member. A control device 10 specifies properties of a liquid in a fuel tank 100 using capacitance of the electrode pairs 33, 38, and 60. The control device 10 specifies the properties of the liquid using the capacitance of the electrode pair 38 at the generation of an electric field of the electrode pair 38 in the fuel and using the capacitance of the electrode pair 60 at the generation of an electric field of the electrode pair 60 in an insulating member.</p> |
