Abstract
Aspects of the present disclosure relate to a sensor device and a method for detecting properties of a liquid. In one example, the liquid is accommodated in an inner chamber. A capacitor arrangement in the inner chamber has spaced, opposing capacitor surfaces so that at least part of the liquid accommodated in the inner chamber is arranged between the capacitor surfaces. An evaluation device for supplying an output signal A depending on a capacitance value of the capacitor arrangement includes an excitation circuit and an evaluation circuit. The excitation circuit has at least one measuring resistor and an AC voltage source configured to apply an AC voltage to a series circuit including the measurement resistor and the capacitor arrangement. The evaluation circuit has an output supplying the output signal A by measuring a voltage across the capacitor arrangement.
