Fernando Cabrera developed the foundational sensor data pipeline for the ISPC-PI-II-2024/Proyecto_hidroponico repository, focusing on scalable hydroponics data capture and reliable team collaboration. He established a clear repository structure, formalized Git workflows, and implemented a sensor testing framework using C++ and PlatformIO. Fernando integrated BMP280 sensor readings with NTP-based real-time clock synchronization, enabling accurate, JSON-formatted data transmission. In the following month, he introduced a SensorDataMQTT class to manage WiFi and MQTT connections, refactored the main setup, and improved error handling and reconnection logic. His work emphasized robust integration, maintainable documentation, and a strong foundation for IoT sensor projects.
