ABSTRACT:
The invention is directed to a system for controlling lawn and garden watering by using electronic sensors to detect the moisture in a lawn. A probe determines the soil water content and powers a signalling device which operates switches for either signalling the need for more water or to stop watering to prevent over-watering. The status of the moisture in the soil is indicated by raising a flag or lighting a strobe light for a visual signal.
