WATER LEVEL SENSING SYSTEM OF APPARATUS

摘要

PURPOSE: A system for sensing a level of a device is provided to sense a level by sensing a capacitance change of a level sensor according to the level of a solution containing in a container, thereby sensing the level. CONSTITUTION: A system(100) for sensing a level of a device comprises a level sensor(120). A container or a solution in the inside of the container is grounded and the level sensor has capacitance proximate to a highest level of the solution in the container larger than 0. A capacitance change of the level sensor is sensed according to the level of the solution in the inside of the container so that the level is sensed.
