Abstract:-The rapid growth of the Internet of Things (IoT) has enabled intelligent monitoring and automation in precise agriculture, especially in greenhouse environments. Existing greenhouse monitoring systems mostly dependent on centralized micro-controllers such as Arduino with basic cloud connectivity, which often face limitations in terms of scalability, flexibility, and system efficiency. This paper presents the design and implementation of a web-based IoT smart greenhouse monitoring and control system with a distributed sensor and actuator node architecture using ESP8266. Unlike conventional systems that use a single centralized controller, the proposed system adopts a distributed architecture consisting of independent sensor nodes and actuator nodes interconnected through Wi-Fi communication, improves flexibility, scalability, real-time response and performance. Environmental parameters such as temperature, humidity, soil moisture, and light intensity are collected using multiple sensor nodes and transmitted to a web server with a database support for real-time storage, visualization, and analysis. A web-based graphical user interface (GUI) allows user to remotely monitor environmental conditions and bidirectional control of greenhouse devices such as irrigation pumps and ventilation systems from any location. The ESP8266 module functions as both the processing unit and communication unit, eliminating the need for additional micro-controllers and reducing system complexity and cost. The implementation results demonstrate reliable real-time monitoring, efficient device control, and improved system scalability compared to traditional centralized greenhouse automation systems. The proposed system provides a practical, cost-effective, scalable, and remotely accessible solution for smart greenhouse management and precision agriculture applications.
