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.

Abstract translation: 提供了一种流体检测装置和流体检测方法。 流体检测装置包括多个电容检测单元和感测电路。 电容检测单元沿着检测方向顺序排列，其中每个电容检测单元响应于流体的淹没而产生阻抗变化，因此产生相应的流体检测信号。 感测电路耦合到电容检测单元，以接收流体检测信号，并根据流体检测信号发送指示流体沿着检测方向的扩散情况的第一状态指示信号。
