Automated Hydroponic Modular System

摘要

The purpose of this document is to evaluate the implementation of technology to the hydroponics technique. Knowing that classical cultivation requires the permanent care of the human being for the irrigation of water and tender of the nutritive solution, it is proposed to use technology to replace the basic functions of crop irrigation through the use of programmable and reprogrammable microcontrollers, thus following the free hardware culture, this paper evaluates a scalable system with sensors, an open source hardware and software platform to interact between analog and digital signals. Within the steps that comprehend the realization of the project, the methodology based on components, provides the appropriate guidance for the analysis and choice of hardware, thus allowing the integration of the electronic components to work along with the appropriate coding; as a result the project will collect the pH value present in the nutrient solution, if the value is not adequate, it will automatically activate the insertion of the solution to the container reservoir, to subsequently operate the automated water irrigation for hydroponic farming. Another relevant aspect is that the project can be improved with other devices that will allow an even greater control of variables and data of hydroponics crops.
