摘要： A non-contact liquid level sensing system for an electric appliance is provided. The electric appliance includes a liquid container for containing liquid. The non-contact liquid level sensing system includes a micro-controller and a plurality of sensors vertically aligned and mounted to the inside of the liquid container. The micron-controller includes a non-volatile memory for storing data. Each of the sensors includes a circuit board, a sensor pad made of a conductive material mounted on the circuit board, and a cover plate made of a dielectric material covering and being in direct contact with the sensor pad. The micro-controller is electrically connected with the sensors, and configured to measure the capacitance between the sensor pad of each sensor and a reference electric potential, and to determine a liquid level in the liquid tank based on the measured capacitance and the data stored in the non-volatile memory of the micro-controller.

摘要： An intelligent electric kettle includes a heating element for heating water contained in the intelligent electric kettle, a sensor for sensing the temperature of the water, and a control unit being configured to collect data during the operation of the intelligent electric kettle. The control unit is also configured to execute a predetermined program and calculate a cut-off temperature based on the data and a predetermined target temperature. The control unit is further configured to turn off the electric power provided to the heating element when the temperature of the water sensed by the sensor is equal to or greater than the calculated cut-off temperature.
