Automação de horta hidropônica utilizando microcontrolador arduíno

Abstract

The supply of food depends greatlyon agricultural expansion, which is rather restricted because the availability of agricultural areas is limited. The hydroponic cultivation system has a competitive advantage and can be seen as an alternative to supply demands for food in the world, because it produceswith low cost inputs (water and nutrient solution), reduced territorial space and nutritional advantage in the vegetables produced. For plants to reach their maximum levels of quality and productivity in the hydroponics system, maximum control over cultivation is necessary. This is possible through microcontrollers such as Arduino, aiming at productive efficiency in this cultivation method. Thus, the objective of this study was to automate the temperature and electrical conductivity control ofthe hydroponic solution used in the cultivationof lettuce, with the aid of an Arduino microcontroller.The results of this study werebased on the comparison of the quality and productivity of the plants grown under water temperature variation from two different treatmentswith the nutrient solution properties used in the hydroponic lettuce cultivation being monitored and controlled.
