Projeto de automação de irrigador agrícola de pivô central usando comunicação LoRa

Abstract

The automated irrigation system reduces production losses due to water déficit when the volume of water from rain is not enough. For the conscious use of water resources, Automated systems need to be increasingly better, more efficient and withre sources that facilitate use by the agricultural producer. In Brazil, in different studies and geography notebooks, there is a gradual increase in the use of the sprinkler irrigation system with the center pivot . The present work aims at the development of the automation system responsible for coordinating the Center pivot irrigation, taking sensor readings and presenting to the user, through a Web interface,which is a very practical way of interacting with the system, a process monitoring. The ESP32 is anOpen-Source and license-free development platform, equipped with Wi-Fi ,Bluetooth and LoRa wireless communication, which is the solution found for the implementation of the proposed automation system. The system consists of two ESP32s, one at the base of the center pivot controlling it, and the second can be up to 15Km away IF they are in direct sight, and can be accessed by the user through a web interface for monitoring. To test the whole process, a model was built to exemplify the irrigator, where ESP32 micro controllers were coupled to control and monitor the system. At the end of the development of this work it was verified that the main objective was reached presenting a system with an easy-to-umderstand interface for the user and na automation in the sprinkler irrigation system with the center pivot.
