Prototype for automating the irrigation system using the arduino UNO R3 prototyping board for water control

Resumo

The use of modern technologies in agriculture is essential, especially for irrigated crops, the sector with the highest consumption of water resources. Given this scenario, the main purpose of this paper is to report on the development of a prototype for irrigation, using low-cost technology based on the Arduino UNO R3 tool to monitor water control at specific times. The research has a qualitative-quantitative approach and was validated in a residence in the city of Castanhal, located in the northeastern region of the state of Pará, Brazil. The materials used to make the prototype were the Arduino model UNO R3, RTC module, solenoid valve, relay module, hoses, and sprinklers. The code developed was programmed in the C++ language, with the first test applied at 09h and the second at 16h, with an interval of 10 seconds. The results obtained from the tests showed that the prototype developed has a good ability to control water for irrigation, being turned on and off at the programmed times. It was also possible to see a high level of efficiency in the use of the Arduino UNO R3 prototyping board, as well as effective communication between the components used, demonstrating that technological tools are important for the management and control of water resources. Therefore, it is possible to conclude that the objective proposed in the project was achieved, since the use of Arduino enabled the creation of a prototype for irrigation, with efficiency for controlling water waste.
