Abstract: Provided are a moisture detection sensor, a defect detection sensor, and a sensor array using the same that make use of moisture-sensitive compounds reversibly reacting to water (moisture) to emit fluorescence, thereby reversibly sensing the moisture within a short period of time and also providing a high degree of sensitivity even to an extremely small quantity of moisture. The moisture detection sensor includes one or more moisture-sensitive compounds selected from the group consisting of Calcein, Calcein-AM (Calcein acetoxymethyl ester), and Calcein blue.
