摘要

The garden ornament, e.g. a gnome, is connected to a system which detects when the water supply to a plant is low and moves the figure about and generates sound through a loudspeaker. The detection system is operated by a hollow metal ball which floats on the surface of the water supply and sinks with it as the water is sued.
