Automatic Sprinkler and Irrigation System
First Claim
1. A sprinkler and irrigation system that is, in each zone, controlled by a controller that allows users to input a Dry Value, which is the soil moisture level when watering is needed, and a Wet Value, which is the soil moisture level when watering is to be stopped, and keeps the soil moisture level between the Dry and Wet Values, comprisinga. a soil moisture sensing means for each zone to detect the soil moisture;
- b. a control means to turn on and turn off valves;
c. a solid state memory means to hold the Dry and Wet Values;
d. the controller that allows users to set the Dry and Wet Values, gets the soil moisture reading from the soil moisture sensing means, and controls the valves through the control means;
e. a means for the controller to communicate with the soil moisture sensing means;
f. a means for the controller to communicate with the control means;
g. a means to supply power to the controller.

Abstract
The present invention provides an irrigation system that allows user to input two soil moisture levels, i.e., the Dry Value and the Wet Value, by conducting a manual watering cycle, i.e., turning on the valves through a Controller when the soil needs watering and turning off the valves when the soil is sufficiently wet. The Controller keeps the soil moisture between the Dry and Wet Values by automatically turning on the valves when the soil moisture reaches the Dry Value, and turning off the valves when soil moisture reaches the Wet Value, at the user-determined desirable watering time periods of the day. In larger areas, the ground could be divided into multiple zones. The Controller could apply different Dry and Wet Values to different zones. The system'"'"'s simplicity is further enhanced by the solar powered wireless moisture sensors.
