Resumen

A prototype of an autonomous multiparameter buoy was designed to address technological limitations in water quality monitoring in aquaculture environments. The objective was to develop a modular and sustainable system integrating photovoltaic energy and wireless communication to monitor critical parameters in real time: pH, temperature, dissolved oxygen, and electrical conductivity. The system consists of an emitter module, receiver module, and a data transmission platform to the cloud. Materials included reinforced PLA and PETG, and electronic components were powered by a 20 W solar panel connected to a 12 V 7 Ah battery. During testing, the prototype demonstrated a 48-hour energy autonomy and reliable LoRa transmission with a 500 m range in the direct line of sight. The modular design facilitates sensor integration and system adaptation to various conditions, benefiting small producers. However, challenges such as component resilience in harsh environments and optimizing energy autonomy under adverse conditions remain, presenting opportunities for future improvements in robustness and scalability. © Los autores.
