To adapt the measuring various kinds of capacity transducer, a capacitance detecting- circuit based-ATmegal 6 is designed in this paper. The sinusoidal wave was adopted to detect phase position of mini-capacity. The capacitance values can be calculated by this kind of circuit which is so flexible that the parameters of circuit can be adjusted according to the capacitor’s size. The theory analysis and simulation prove that the multiple-interface sensor have excellent performance.
