This simple device is ideal for confused that leaves the open windows wide and, when the water leaves, forgets to close them.

The heart of the project is the thyristor TS08 which is initially open. When a drop of water falls on the interlaced tracks takes place a partial conduction of current that reaches to shoot the floodgate and to make sound buzzer.
