Automatic Control System for Climate Variables to Optimize Greenhouse Crop Yields

Introduction: The article derives from the research “Design of a system for the control and automation of temperature, soil moisture, and relative humidity to optimize greenhouse crop yields at Corhuila” conducted at Corporación Universitaria del Huila between 2016 and 2017.Aim: To improve growth rates of greenhouse crops.Methods: The study was based on a comparison of growth and number of fruits between greenhouse and outdoor tomato crops; said items were monitored weekly by direct observation of the two groups of crops.Results: Development during the first five weeks was similar; as of the seventh week, the greenhouse crop had 38% more branches, equal number of fruits and was 28% higher; on week 13, the differences increased to 64% in the number of branches, 65% in the number of fruits and 55% in height.Conclusion: It was proved that the implementation of this technological solution can promote an increase in the growth and production rate reached by plants.Originality: Development of an electronic system for the agricultural sector in an intermediate region of Colombia to improve the efficiency of crops.Limitations: The lack of Internet access made it impossible to implement a web-based control system.
