Controle e monitoramento remoto de sistema hidropônico utilizando plataformas open source.

Abstract

More and more, small and medium producers have increased the demand for growing vegetables, as it is an alternative of consistent extra income due to the sharp increase in demand for products grown mostly in ecological production. Among the production models, hydroponics stands out, which is very versatile with respect to installation and handling, presenting several advantages, such as the need for no soil preparation and the possibility of installing it in small or unusable environments for other types of crops. For medium and large commercial applications, there are some special cares regarding calculations, which define parameters such as pump power, greenhouse dimensions, among others. In this sense, the present study aims to develop a remote monitoring and control system, via mobile application, for hydroponic cultivation of vegetables through an Arduino microcontroller and Esp. For this purpose we started from the problematic of hydroponic cultivation and its current difficulties inherent to its form of development, suggesting automation methods based on monitoring and control that aim to mitigate or, in some cases, completely extinguish the dependence on manual work and constant monitoring by the producer. The results showed that the cultivation of hydroponic lettuce with the use of the application under the conditions studied, presented an excellent potential of viability, constituting an alternative for producers interested in the use of the system developed. However, it is necessary to emphasize the need for guidance from qualified technicians in order to obtain success in hydroponic cultivation and that this project requires investments, in the amount of approximately R$ 1,600, in relation to the total value of a hydroponics represents 10 to 15% of the value, which is relatively low. It is concluded that the implementation of the monitoring and control system for hydroponic cultivation is feasible, and allows a return in the medium term, what makes this possible is the more accurate and real- time monitoring of production and optimization of the use of inputs.
