Abstract
A sensor is provided for detecting relative amounts of components within a mixture. The sensor includes a dielectric transducer comprising a first conductive rod and a second conductive rod; an oscillator configured to apply a voltage to the first conductive rod; an amplifier configured receive a voltage from the second conductive rod as input; and a controller configured to periodically sample an output voltage of the amplifier to generate a plurality of sample voltages, compare the sample voltages against distinct voltage values for identifying each of the components to determine the relative amounts of the components.
