ABSTRACT:
An automatic moisture sensing and watering system detects a moisture level within the soil. The automatic moisture sensing and watering system may be implemented in combination with a conventional automatic watering system to accurately control a moisture content of a plot of soil. Since a plant draws water directly from the soil, the automatic moisture sensing and watering system is adapted for controlling the moisture content of the soil itself, by measuring the moisture content within the soil. The watering period of an automatic watering system may be changed, based upon a detected moisture content within a plot of soil. Alternatively, an amount of water to be applied at a next watering period may be changed, based upon a detected moisture content within the plot of soil.
