An intelligent non-contact liquid level sensor is for detecting whether there is liquid through the water induction capacitor. When there is no liquid to approach the sensor, the sensor will generate some static capacitance due to the capacitor distribution; when the liquid rises slowly to approach the sensor, the liquid parasitic capacitor will coupling to this static capacitor so that the terminal capacitance of the sensor will increase; The changing capacitance signal will be input control IC and reach the signal switch, then transform the changing capacitance value into a variation of a certain electrical signal. Using a certain algorithm to detect and judge the degrees of the variation; when the variation has exceeded a certain threshold, then it means the liquid level reached the sensing point
