Claim:
1. A fluid detection apparatus, comprising: a plurality of capacitive detection units, sequentially arranged along a detection direction, wherein each of the capacitive detection units generates an impedance variation in response to a submergence of a fluid and accordingly generates a corresponding fluid detection signal; a sensing circuit, coupled to the capacitive detection units so as to receive the fluid detection signals and emit a first status indication signal indicating a spread circumstance of the fluid along the detection direction according to the fluid detection signals; and a smart power supply, coupled to the sensing circuit, wherein the smart power supply is configured to supply power to a fluid regulating apparatus and detect a power supply condition to determine whether the fluid regulating apparatus is in a operating condition, wherein the smart power supply decides whether to reset so as to restart the fluid regulating apparatus according to the first status indication signal and the power supply condition.
