Operation mode
Smart contactless liquid level sensor in the water sensing capacitor to detect the presence of liquid. When no fluid proximity sensor, a capacitance distribution due to, sensors have a limited static capacitance. When the level slowly raised to near the inductor, a parasitic capacitance of the liquid to be coupled to the static capacitor, resulting in a large capacitance of the inductor. Capacitance signal is then input to the changed control IC, for signal conversion, the signal will change. Capacitance variation is converted into an electric signal, and an algorithm to detect and determine the extent of the change. When the change exceeds a certain threshold, the level is considered to reach the sensing point.
