The objective of this study was to develop an electronic controller for microclimate control in greenhouses, as well as to verify if the automated control system affects the productivity of two varieties of lettuce "Lactuca sativa". The control system was developed based on the Atmega 2560 and compatible transducers. An experimental field analysis was carried out over a production cycle for two lettuce varieties. The experimental results showed that the designed equipment worked according to the implemented programming algorithm. However, the ventilation, nebulization and shading actuators did not control environmental variables, due to under sizing. The irrigation process was correctly controlled throughout the experimental period. The electronic controller promoted increase in the productivity of lettuce varieties. There was increase of 28% in total fresh weight; 10% in stem diameter; 7 and 8% in height gain and average diameter, respectively.

“…Geotechnical monitoring systems tend to be comprised of groups of sensors in thermometric wells along the routes of the pipelines; the sensors are linked with wired or wireless technologies, and measurements are obtained using web-based software. Modern approaches to the design of distributed systems are listed in [2][3][4]. In [5] is noted that the quality of an open atmospheric optical channel is affected by the frequency of weather changes, fluctuations of supports, scintillation.…”

Extensive, but remote oil and gas fields of the United States, Canada, and Russia require the construction and operation of extremely long pipelines. Global warming and local heating effects lead to rising soil temperatures and thus a reduction in the sub-grade capacity of the soils; this causes changes in the spatial positions and forms of the pipelines, consequently increasing the number of accidents. Oil operators are compelled to monitor the soil temperature along the routes of the remoted pipelines in order to be able to perform remedial measures in time. They are therefore seeking methods for the analysis of volumetric diagnostic information. To forecast soil temperatures at the different depths we propose compiling a multidimensional dataset, defining descriptive statistics; selecting uncorrelated time series; generating synthetic features; robust scaling temperature series, tuning the additive regression model to forecast soil temperatures.

RESUMO:O cultivo hidropônico apresenta-se como uma técnica de grande potencial para o uso eficiente da água, pois demanda menor volume de água em comparação ao plantio convencional. Se o cultivo hidropônico for praticado em ambiente protegido, o gasto de água deve ser ainda menor em relação ao cultivo a céu aberto. Assim, o monitoramento contínuo das condições internas do ambiente permite estabelecer uma faixa ideal de temperatura e umidade relativa do ar para o crescimento das plantas. Para o sucesso na hidroponia torna-se imprescindível o adequado manejo da solução nutritiva, principalmente no que diz respeito ao monitoramento da temperatura da solução, pois esta influencia diretamente na concentração de oxigênio dissolvido, condutividade elétrica e pH. Tais parâmetros podem ser facilmente monitorados e armazenados por longos períodos em sistemas de aquisição de dados, denominados dataloggers, porém, tais equipamentos são de elevado custo. Assim, no presente trabalho apresenta-se a confecção de um dispositivo físico na plataforma Arduino. O sistema foi testado em ambiente protegido, aproveitando-se um experimento com coentro cultivado em sistema hidropônico DFT (técnica do fluxo profundo) sob diferentes lâminas de solução nutritiva, onde foram obtidos dados de temperatura e umidade relativa do ar e temperatura da solução nutritiva. Foi utilizada uma placa Arduino Uno, na qual conectaram-se os sensores DHT22 (temperatura e umidade relativa do ar) e o DS18B20 (temperatura da solução nutritiva). Utilizaram-se ainda os módulos de leitor de cartão SD para armazenamento dos dados e do relógio de tempo real (RTC) para fornecer a data e horário do armazenamento dos dados. O material utilizado para confecção do sistema foi facilmente comprado pela internet e de baixo custo. Durante o período de monitoramento dos dados, as temperaturas da solução nutritiva e do ar não ultrapassaram de 30 e 35ºC, respectivamente. Os valores de umidade relativa foram sempre superiores a 60%.
