In the last decade, climate changes decreased precipitation and increased soil temperature. Global warming increased fire frequency and severity in orchards bushfires. Mangoes are trees that drop leaves once they have dried creating an ideal environment for rapid soil fire spreading. As wildfire eradication schemes at farm level are a priority in our country, a sprinkler irrigation system was installed in an experimental orchard. Water management produced more fruit and established grass within the trees canopy. Automated valves were designed to water the orchard by using buried PVC pipes. The motorized butterfly valve was opened by a starting pulse letting the water flow and was closed after receiving another pulse when the irrigation period was over. Several valves worked together to provide the water required for one hectare being the energy provided by a lithium ion battery charged with a micro turbine. Optimum energy management during valve opening and closure can only be performed under minimum friction. Wireless transmission turns off the pump to optimize this process. The sprinkler irrigation kept moisture within the soil providing a wildfire protection system.
