Desenvolvimento de módulos de sensoriamento para a supervisão e controle de fazendas verticais

Abstract

The usage of new technologies in industry and farms has being leading a revolution in the way of acting in several fields, including agriculture. The area, currently called Agriculture 4.0 or Smart Farms, promotes the integration of several sensors and equipment aiming to improve performance, in which the previously restrict knowledge from the industry and the telecommunications area, can be applied in the most diverse contexts. One of these contexts, linked to Agriculture 4.0, are the greenhouses and the vertical farms monitoring, where all variables which are relevant to the plantation are monitored in a controlled environment, using communication networks and data processing. Given the diversity and systems cost for this application, it is proposed in this work a monitoring system development for low-cost modular indoor planting, aiming to be modular and accessible to small farmers. To develop the prototype, modules with Wi-Fi connectivity were used, which enabled the communication with the central database, responsible for storing the data coming from the sensors. An HTML website and a Power BI project were created for data visualization. This solution enables remote and automated monitoring of soil and environmental conditions. As a result, a module with an ESP microcontroller was developed to collect and transmit data on soil moisture, air humidity, and temperature. The information is stored in a Wi-Fi-connected database for future use.
