“…Despite the modernization of agriculture in recent years, many farms, mostly small and medium-sized ones, still employ manual irrigation because automated systems typically involve high installation and maintenance costs, making it difficult for small and medium-sized producers to use them. Grah et al (2012) conducted an assessment of irrigation systems and concluded that automated systems were better than conventional methods because they save water and increase crop yields. The authors were also concerned with the lack of electricity in some regions and thus developed an autonomous irrigation system that uses hydraulic-mechanical power as an alternative irrigation pumping system for places lacking electricity.…”

Irrigation is a practice that increases productivity and enables the expansion of agricultural borders. This practice should be well managed to ensure the efficient use of water by plants, and such management requires specialized labor, which increases operating costs. Therefore, the main objective of this study is the implementation of an automated irrigation system that considers factors ranging from water demand to the operation of the system. Because the daily water demand is determined by crop evapotranspiration, a low-cost weather station was developed to acquire data daily. Such data can be used to estimate the reference evapotranspiration (ET0) using the Penman-Monteith model of the Food and Agriculture Organization (FAO). Thus, by combining the amount of water required by a crop with the physical and hydraulic properties of the soil and the hydraulic properties of the irrigation system, it was possible to determine the daily frequency and amount of time required for the system to operate to meet the water requirements of the crop without undergoing stress from a deficit or an excess of water. The management/monitoring system was designed and implemented to allow the user to access data remotely through an online application. This application enables the real-time transmission of irrigation-related data, such as weather station data and system logs, obviating the need for the user to be present at the crop site. This allows the supervision of many areas simultaneously with low cost

“…Losses of water through evaporation or drift is minimized, as well as fungicidal diseases. The volume of water for localized irrigation is smaller when compared to other application methods, being an advantage for places where water resources are scarce or that face conflicts over water use (Grah et al, 2012).…”

Solar energy is a clean and renewable energy production option and can be applied to pumping water. Pumping water with photovoltaic solar energy is one of the technologies that has stood out in the country. In this context, the work aimed to evaluate the different methods of a drip irrigation system as a function of the use of an indoor amorphous photovoltaic pumping system, without electrical energy storage. The study was installed at the State University of Western Paraná. Voltage and current data were generated by the photovoltaic panels; solar irradiation was measured by the pyranometer device; the water pump flow rate was determined using the flow meter and in-line drip tube types. Irrigation performance was determined by the water distribution uniformity coefficients (CUD) and Christiansen’s uniformity coefficient (CUC). Tests were performed on open and partially cloudy days. The experiment totaled 40 sampled data, half being collected on sunny days and the other half on partially cloudy days, at 9:45 am; 11:00 am; 1:30 pm and 3:00 pm. The methodology had the greatest influence on the CUD value. For the CUC parameter, the values were approximately 89% for the studied methods. Values remained under control for the Shewhart graph, but with the process capacity index affected.

“…Dessa forma, na irrigação localizada o volume de água utilizado é menor quando comparado aos demais métodos de irrigação, sendo vantajosa sua aplicação em locais onde há limitação ou escassez de recursos hídricos ou ainda que enfrentem conflitos pelo uso da água. (GRAH et al, 2012) Um dos principais fatores de produção na agricultura é a água, sendo que cada espécie de planta necessita de um adequado nível de água no solo para atender suas necessidades fisiológicas (MANTOVANI et al, 2012).…”

Para averiguação do funcionamento do protótipo em campo o experimento foi elaborado com 4 Tratamentos de potenciais de água no solo e 3 cultivares de alface, em delineamento inteiramente casualizado em esquema de parcelas subdivididas, com 4 repetições. Para a irrigação da alface, foram instaladas 12 linhas laterais de tubos gotejadores sobre 12 canteiros, cada um com 1 m de largura e 10 m de comprimento. A automação consistia de 4 válvulas solenoides e um conjunto motobomba que, acionados automaticamente por sinais analógicos (emitidos pelos sensores de umidade do solo instalados nos canteiros de cada Tratamento), aplicavam as lâminas de irrigação. De acordo com os resultados obtidos, o protótipo aplicou com excelência diferentes volumes de água nos Tratamentos, conforme o potencial de água no solo adotado. Houve diferença estatística na produção da alface. A automação funcionou normalmente por um período de 45 dias ininterruptos, não apresentando falhas ou danos no sistema. Concluímos que é possível realizar com eficiência a automação total da irrigação e do manejo da água com baixo custo, dispondo de equipamentos eletrônicos facilmente encontrados no mercado, obtendo uma considerável redução no uso da água e energia.

AUTOMATION OF LOCALIZED IRRIGATION AND WATER MANAGEMENT IN THE CULTURE OF LETTUCE WITH ARDUINO UNO R3 2 ABSTRACT The objective of the experiment was to verify the efficiency of a prototype for irrigation management according to different soil water potentials, based on the Arduino model Uno R3 microcontroller. In order to verify the functioning of the prototype in the field, the experiment was elaborated with 4 treatments of water potentials in the soil and 3 lettuce cultivars, in a completely randomized design in subdivided plots scheme, with 4 replicates. For irrigation of lettuce, 12 lateral lines of dripping tubes were installed on 12 beds, each 1 m wide and 10 m long. The automation consisted of 4 solenoid valves and a motor-pump assembly that, triggered automatically by analog signals (emitted by the soil moisture sensors installed in the beds of each treatment), applied the irrigation depths. According to the results obtained, the prototype applied with excellence different volumes of water in the treatments, according to the potential of water in the soil adopted. There was statistical difference in lettuce production. The automation worked normally for a period of 45 uninterrupted days, with no system failures or damage. We conclude that it is possible to efficiently carry out total automation of irrigation and water management with low cost, using electronic equipment easily found in the market, and thus obtaining considerable reduction in the use of water and energy. Keywords: Capacitive sensor; microcontroller; irrigation management.
