A circuit for measuring an unknown capacitance includes a reference capacitor having a known capacitance, an oscillator timing circuit, a variable frequency oscillator and a microcontroller. The oscillator timing circuit includes switches which selectively couple the unknown capacitance and the reference capacitor to the oscillator timing circuit. The variable frequency oscillator generates time varying signals which vary in frequency proportionally to the unknown capacitance and reference capacitor selectively coupled to the oscillator timing circuit. The microcontroller receives the time varying signals from the oscillator, and compares the periods of the time varying signals to determine the value of the unknown capacitance.
