Open Irrigation Controller System
The goal of this project is to create a wireless and networked irrigation control system for greenhouses. The end goal is to provide a user-interface (UI) from which a farmer could see a map of their nodes, monitor their sensor readings, actuate valves in real-time, develop a schedule, and implement logic in response to sensor readings.
