Abstract
This work consists in the development of a system for data acquisition of parameters in an agricultural application. For this, the system includes the monitoring of soil moisture and atmospheric sensors (temperature and relative humidity), in order to provide subsidies to farmers in decision-making, aiming at a future implementation of an automated irrigation system, with minimization of waste of water resources. Data acquisition is carried out by means of sensors connected to a microcontrolled system, and the signals are transmitted through a radio frequency module using LoRaWan™ protocol. Data is received at a gateway and made available in the cloud, applying Internet of Things (IoT) concepts, and can be monitored in real time in an academic interface. Additionally, the data can also be monitored through a simplified interface accessible through an app developed specifically for the application.
