Abstract:-
The practical deployment of Internet of Things (IoT) technologies in greenhouse agriculture requires reliable hardware implementation in addition to real-time monitoring and control capabilities. Many existing IoT-based greenhouse systems are developed using breadboard-based prototypes and loosely connected components, which are prone to connection failures, increased maintenance, and reduced suitability for long-term agricultural use. To address these limitations, this paper presents the implementation of a printed circuit board (PCB)-based IoT smart greenhouse monitoring and control system using the ESP8266 microcontroller with web server integration. The proposed system emphasizes hardware-level design and deployment by developing custom PCB layouts for both sensor nodes and actuator nodes. The PCB-based sensor node integrates environmental sensors for measuring temperature, humidity, soil moisture, and light intensity, along with the ESP8266 for data processing and wireless communication. The actuator node is also implemented on a custom PCB and interfaces with relay circuits to control greenhouse equipment such as irrigation pumps and ventilation systems. The collected environmental data is transmitted through Wi-Fi to a web server, where it is stored in a database and made available through a web- based monitoring interface. This enables users to remotely observe greenhouse conditions and control devices as required. The use of custom-designed PCBs improves system compactness, reduces wiring complexity, enhances connection stability, and increases overall reliability compared to prototype-level implementations. The system was fabricated, assembled, and deployed in a greenhouse environment to validate its functionality under real operating conditions. Experimental observations confirm that the PCB-based system operates reliably, provides stable wireless data communication, and effectively controls greenhouse devices. The implementation demonstrates that PCB-based integration significantly improves system robustness and deployment feasibility. The proposed system offers a cost-effective, reliable, and deployment-ready IoT solution for smart greenhouse monitoring and control, supporting the advancement of precision agriculture and sustainable farming practices.
