Pablo Napantoja developed a rain sensor integration for the ISPC-PI-II-2024/Proyecto_hidroponico repository, focusing on environmental monitoring within a hydroponics system. He designed and implemented a main Arduino sketch in C and C++ to read sensor data and drive both LED indicators and an LCD display, providing real-time feedback on rain detection. To ensure reliability, Pablo established a PlatformIO project scaffold and introduced unit tests that validate sensor readings and automated feedback mechanisms. His work emphasized maintainability and repeatable builds, resulting in a robust embedded system that streamlines diagnostics and monitoring for automated hydroponic environments, though completed within a short timeframe.
