I found that you can make a simple alarm for water. a wooden clothes pin [spring type] two screws a battery, some wire and a buzzer.
Think simplicity not complicated! make the thing by drilling holes in both pieces of the spring type clothes pin. put a machine screw in both with a nut on the outside so that both screw heads touch when the clothespin is shut. attach a wire from the battery [ 6 volt lantern battery] to one side of the clothes pin with another nut. attach another wire from the other terminal of the clothes pin with a nut to a 6 volt buzzer. one more wire from the buzzer back to the other terminal of the battery. Now for the TECHNICAL part. put a non coated regular aspirin between the terminals of the clothes pin. put the clothes pin where water normally collects. when the aspirin tablet melts the contacts close and set off the buzzer.
