A liquid level sensor is arranged to sense a quantity of a liquid within a reservoir. The sensor includes a plurality of discrete sensing units disposed within the reservoir. Each of the plurality of sensing units has an output, and the output has a first value when the sensing unit is immersed in a liquid and a second value, different from the first value, when the sensing unit is not immersed in a liquid. A signal generator is operably electrically coupled to each of the plurality of sensing units. The signal generator is operable to provide an excitation signal to each of the plurality of sensing units. Each of the plurality of sensing units is operable to provide the output responsive to the excitation signal.
