Utilização de Arduíno em sistema de irrigação automatizado de baixo custo

Abstract

The present work was carried out in the campus of the Federal University of Southern Frontier (UFFS), Laranjeiras do Sul - PR. It aimed to set up an automated irrigation system for the management of irrigation of vegetables. It used the Arduino platform to process signals sent by the YL-69 soil moisture sensor and retransmit the opening and closing data of a solenoid valve connected to the hydraulic part of the irrigation system. Soil sensor data were transformed to percent moisture for better interpretation. It was necessary to perform the field capacity (CC) determination to obtain the result of 37% humidity corresponding to the water availability factor f for the CC of 40.42%. This system aims at reducing the labor force used to manage irrigated crops, minimizing losses due to the uncontrolled or inefficient use of water, reducing the waste of natural resources and thus improving the final quality of the product. After some tests performed with the system it was clear the operational ease and convenience that the system provided.
