<p>A sensor device may be configured to detect a level of liquid, a concentration of a specific substance included in the liquid, and a temperature of the liquid. The sensor device may comprise a substrate, a level electrode configured to be disposed on the substrate and detect the level, an electrode for liquid quality configured to be disposed on the substrate and detect the concentration, a temperature electrode configured to be disposed on the substrate and detect the temperature, and a reference electrode configured to be disposed on the substrate and maintain a reference electric potential. The reference electrode may be disposed at least between two of the level electrode, the electrode for liquid quality and the temperature electrode.</p> |
