GreenHouse — AST High Distinction

GreenHouse was the final project for AST, a URJC subject where the codebase evolved through successive practical assignments. The goal was to build a greenhouse management system in C++ using object-oriented programming, not just isolated exercises. The final version connected users, sensors, cameras, hardware interfaces, persistence, documentation, and UML design into a single system.

The architecture is organized around a main GreenHouse class that coordinates AlarmSensors, ManageCameras, MonitoringSystem, and UsersServer. The system includes Admin, Employee, and Guest users; a user database/server layer; RGB and temperature cameras; sensors for temperature, air quality, humidity, pressure, light, and pH; and hardware abstractions for screen, keyboard, and switch. It also persists users and sensors in text and binary files such as users.txt, users.dat, sensors.txt, and sensors.dat.

A key part of the project was the learning curve. Around the middle of the course, after receiving direct feedback that the current work would objectively not go beyond a 5/10, I used that as a turning point. I reviewed where my C++ and OOP design were failing, rebuilt the architecture with more discipline during the Easter break, improved documentation and diagrams, and turned the final delivery into my first Matrícula de Honor. It remains one of the academic projects I am most proud of because the result came from correcting real design mistakes, not from starting with an easy path.
