Automatic control of drip irrigation on hydroponic agriculture: Daniela tomato production

Abstract:

The irrigation control and monitoring of the involved variables in the plant growth are actions that farmers must implement in their crops to save water resources and assessing the growth of the Daniela tomato plant. This work presents the control drip is applied to hydroponic farming in which is developed an interface between human and machine in a free software allowing continuous monitoring of moisture, pH, temperature and electrical conductivity of soil through the sensors housed in the crop root zone also, the controller performs the conditioning sensors, actuator control resource to irrigate water, and nutrient solution, and monitoring via web. The field implementation of the system is carried out in a tunnel-type greenhouse designed under the requirements of a hydroponic system. Finally to show the results we evaluate two experiments: Experiment one: determining hydric resourses, and nutritional requirements needed by the culturing based on monitoring of physical variables. Experiment 2; assess how media type tomato fruit have more weight and diameter.
