This research presents a real-time smart irrigation system designed to meet the challenges of modern agriculture using emerging technologies such as embedded systems, the Internet of Things (IoT), and real-time communication protocols such as HTTP and WebSockets. The innovation lies in the integration of these technologies to create a complete solution for precise irrigation. The system features a modular architecture composed of three functional layers: the IoT device layer, the WebSocket layer, and the web interface layer. The IoT device layer uses ESP32 microcontrollers and IoT sensors to collect environmental data such as temperature, soil moisture, and water level. The WebSocket layer facilitates real-time communication between IoT devices and the web interface, while the web interface layer provides a user-friendly interface enabling users to monitor and control irrigation remotely. The system was evaluated through simulations and practical experiments to demonstrate its effectiveness. The results show that the system enables real-time monitoring of irrigation parameters, optimized management of water resources, and improved crop yields. In addition, the system promotes sustainability by reducing water wastage and encouraging more environmentally friendly farming practices. This research proposes an innovative solution for smart irrigation that could help meet the challenges of food security and the Sustainable Development Goals.
