An Automation Proposal with the Use of the Arduino Platform in the Rational Use of Water in the Irrigation Process

The rational use of water is a practice that seeks conscientious and controlled consumption, which uses the natural resource only as necessary for each specific activity. For the improvement of the practice, the help of new technologies is important. The objective of this work was to present the results obtained with the use of an Arduino prototype in automated irrigation, to contribute to the development of automated systems in the rational use of water. Thus, it was sought to use only the necessary amount of water for the plant in the irrigation of the system. The work reveals an applied nature, a qualiquanti approach and an inductive scientific method. Tests were carried out to verify the functioning of the prototype, up to operation during a period of 60 days with readings every 1 hour. The parameters to define the intervals for wet soil (0 -- 500), and dry soil (501 -- 1023) were adopted from the values provided by the manufacturer of the moisture sensor used in the project. As a result, the soil remained within the ranges for dry soil and wet soil without acute values for both. It is concluded that irrigations were carried out in times of dry soil without water supply to the plant in times of moist soil. The rational use of water in the irrigation system in which the prototype was applied was put into practice.
