Wireless Irrigation Controller with Solar Power

The patent replaces the mechanical wiring system with a wireless communication system. The controller and solenoid valves/pumps communicate via radio frequency signals instead of physical control wires, eliminating the need to bury cables while maintaining reliable control signal transmission. This substitution resolves the contradiction by removing the installation complexity associated with buried wires while preserving the reliability of control signal delivery.

The patent introduces wireless communication signals as an intermediary medium to transmit control commands between the controller and water flow control devices. Instead of direct physical connections through buried wires, RF signals serve as the intermediary carrier, enabling control without the infrastructure of underground wiring while maintaining system reliability.

The patent implements preliminary charging actions by incorporating solar panels that continuously charge the battery during daylight hours. This preliminary energy accumulation ensures that sufficient power is stored before needed, extending the operating duration of the wireless controller without requiring frequent manual battery replacements or larger initial battery capacity.

The system employs self-service power generation through integrated solar panels that automatically recharge the battery. The controller monitors its own power status and manages charging/discharging cycles autonomously, eliminating the need for external power connections or manual intervention. This self-sustaining approach resolves the operating duration limitation by continuously replenishing power from renewable solar energy.
