an autonomous, solar-powers irrigation system
The irrigator does not require a connection to the water or the electric grid. A solar panel is used to power a low voltage pump which sustains the water flow. The water is taken from a tank, ideally a rain-water harvesting tank. A set of magnetic valves distributes the water on different zones. A programmable micro-controller is used to control the system. The condition of the soil is monitored using moisture sensors which trigger the watering if required – and avoid wasting water through over-watering.
