Sistema Automático de Monitoramento e Atuação para Produção Hidropônica

Abstract

Environmental impacts resulting from climate change represent one of the greatest challenges faced by contemporary society. Agriculture, an activity highly vulnerable to climatic variations, is directly affected by soil degradation, water scarcity, and the effects of global warming. In this context, hydroponics emerges as a sustainable alternative, enabling soilless cultivation and more efficient use of water and nutrients. The integration of hydroponics with the Internet of Things (IoT) can enhance automation and control over cultivation conditions, contributing to the sustainability and economic viability of agricultural production. This work proposes the development of an automatic monitoring and actuation system for hydroponic cultivation based on the NFT (Nutrient Film Technique) method. The system uses ESP32 microcontrollers, low-cost sensors, and the MQTT protocol for communication. The proposal aims to democratize access to sustainable cultivation technologies suitable for both small and large-scale producers.
