Item Monitoramento para automação de processos em cultivos hidropônicos: uma revisão bibliográfica sistemática(2024-03-07) Silva, Iracema Carla Calixto da; Sousa, Emanoel Di Tarso dos Santos; http://lattes.cnpq.br/3682039140895268; http://lattes.cnpq.br/8422413675003216In the current context of global hunger and exponential population growth, implementing technological practices to increase agricultural productivity and reduce waste is crucial. This paper conducted a bibliographic review on the use of monitoring technologies for environmental variables and nutrient solution in hydroponic farming, aiming to identify advancements in process automation for agricultural production in this modality. 82 sources were consulted between 2010 and 2023, identifying 16 works that used hardware and software technologies for automation in hydroponic systems. Controllers like ESP32, Arduino Nano, and Arduino Mega were employed to monitor and control environmental and nutrient solution variables, while peristaltic pumps and solenoid valves ensured precise dosing and water flow control. Software such as C++, Dart, Matlab, Arduino IDE, LabView, Blynk, and ThingSpeak were used for programming and data integration, while online platforms like Firebase, Flutter framework, and MQTT were employed for real-time data storage, visualization, and communication. Although offering advantages such as increased efficiency and resource savings, the use of these technologies faces significant challenges, including the need for specialized technical knowledge and connectivity dependence.Item Hidroponia de baixo custo e fontes alternativas de água na produção de hortaliças(2018) Bartusch, Victor Pedrosa; Santos Júnior, José Amilton; http://lattes.cnpq.br/2839547928353699; http://lattes.cnpq.br/3865227333865612Salinization problems in semi-arid regions make hydroponics a viable crop alternative for agricultural production. In this sense, the objective of this study is to evaluate the water relations of the parsley under different concentrations of salts. Two experiments were carried out in greenhouse, in the Experiment 1, in the factorial scheme (6 x 4) with six salinity levels of the nutrient solution (1.7; 2.7; 3.7; 4,7; 5.7 and 6.7 dS m-1), prepared on the basis of four cationic natures (NaCl, CaCl2, KCl and MgCl2). No experiment I the water of the evapotranspirated blade was replaced with water supply and without experiment II a replacement was made with brackish water based on the cationic natures mentioned above according to treatments. It was verified that with the increase of the electrical conductivity of the nutrient solution, the cationic natures of the water influence the efficiency of water use in the production of fresh and dry mass of the aerial part.
