Sistema de monitoramento em tempo real do matricial do solo

Abstract

The present work aims to develop a real-time monitoring system of sensors that measure the soil matric potential. Based on the concepts of the Internet of Things (IoT), the integration of data collection with a storage on a web server was carried out, where sensor data is sent via Wi-Fi connection and the MQTT protocol, allowing real-time access and visualization of data. Aiming at greater reproducibility, the system was prototyped using the NodeMCU-32S ESP32 platform, which was responsible for eading the data from the sensors and sending them for remote monitoring. Through constant monitoring, it is possible to have greater control of the raw materials needed for agricultural production. For water resources, which are increasingly scarce in various regions of the planet, knowledge of the necessary conditions to trigger their use in the irrigation process is of great importance. With the necessary data, we can avoid waste, as well as having the knowledge of how much and for how long it is necessary to irrigate. Monitoring facilitates the management of this very important resource, and its control is only possible using sensors that help to verify soil moisture, resulting in a better use of available water resources.
