Automatic Sprinkler and Irrigation System

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, comprising

• a. 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.
