Abstract:
A fluid detection apparatus and a fluid detection method are provided. The fluid detection apparatus includes a plurality of capacitive detection units and a sensing circuit. The capacitive detection units are sequentially arranged along a detection direction, wherein each of the capacitive detection units generates an impedance variation in response to the submergence of the fluid and accordingly generates a corresponding fluid detection signal. The sensing circuit is coupled to the capacitive detection units so as to receive the fluid detection signals and send a first status indication signal indicating a spread circumstance of the fluid along the detection direction according to the fluid detection signals.
