COST OF PRODUCING A SMART IRRIGATION SYSTEM WITH ARDUINO

Abstract

The introduction of technology into production processes in the agricultural sector is a reality experienced in all regions of Brazil. This technology has been helping to develop the rural sector, relieving production costs and reducing the execution time of certain activities within production systems. This project aimed to produce an automated automation system with Arduino, developed in observation of the climatic particularities of the municipality of Lábrea, Amazonas, evaluating production costs and making implementation economically viable for farmers. In the construction of the project to automate the safety process used are soil moisture sensors, an Arduino board, a breadboard, a solenoid valve, a relay module, connection and power cables. The sensors were assembled on the breadboard and the Arduino was programmed with adjustments to the code for accurate reading of the sensors and control of the solenoid valve according to soil humidity. The total production cost was R$265.08, all components were purchased through companies based in Manaus, Amazonas. For automatic safety, the level of humidity present in the soil was programmed to activate and deactivate the solenoid valves, respectively a minimum of 40% and a maximum level of 100%. The prices of the components used in the system were 45% higher when compared to the prices of products available on online websites. The project presented economic predictions for use in small gardens, offering a promising solution, reducing costs and minimizing environmental impact.
