Abstract
A viscosity and corrosivity sensor apparatus includes a substrate upon which one or more electrodes are configured. The electrode(s) are exposed to a liquid, such as automotive oil. An oscillator can be connected to the electrode, wherein the oscillator assists in providing data indicative of the corrosivity and data indicative of the viscosity of the liquid in contact with the electrode(s). A viscosity and corrosivity sensor is therefore provided in the same package.
