Abstract
A liquid level sensor and a method for sensing a liquid level adapated to a liquid storage container are provided. The liquid level sensor includes a pluraity of sensing electrodes and a liquid level determining circuit. The sensing electrodes are arranged on a side wall of the liquid storage container, and correspond to different liquid levels. The liquid level determining circuit is coupled to the sensing electrodes, and scans capacitance values of the sensing electrodes, so as to determine a liquid level of a liquid in the liquid storage container based on the current capacitance values of the sensing electrodes.
