Sistema automatizado para hidroponia sustentável: uma abordagem aplicada ao clima do Amazonas

Abstract

This work presents the development of an automated system for controlling hydroponic cultivation of vegetables, designed to operate under the specific climatic conditions of Manaus, Amazonas, a region characterized by high relative humidity and elevated temperatures. The proposed solution utilizes the Arduino platform to integrate sensors that monitor variables such as water flow, pH, and nutrient solution temperature, aiming to maintain suitable conditions for plant development. The system is powered by a photovoltaic panel, with energy stored in batteries to ensure continuous operation, even during nighttime periods. The proposed automation seeks to optimize hydroponic cultivation by addressing the environmental challenges of the region, such as managing high evaporation rates and maintaining nutrient solution stability in a hot and humid environment. By combining automation technologies and renewable energy sources, this project illustrates how smart and sustainable agricultural solutions can be implemented to meet regional demands and promote greater efficiency in hydroponic management.
