Description
This project have an arduino MEGA, a board designed for the electronic actuation from control signal from themicrocontroler and solenoid valves to cointrol the water flux for final irrigation system. The control is a on-off system with a closed-loop topology. The feedback sensors is the moisure capacitive sensors for control.
