This paper describes the design and development of a PLC-SCADA-based smart greenhouse automation system that integrates solar energy. The goal is to improve agricultural productivity while ensuring energy efficiency and sustainability. The system continuously monitors and controls key greenhouse factors such as temperature, humidity, soil moisture, and light intensity using industrial-grade sensors connected to a Programmable Logic Controller (PLC). A SCADA-based supervisory interface provides real-time data visualization, remote monitoring, alarm management, and manual control. The control logic uses PLC ladder programming, which allows devices like ventilation fans, water pumps, misting units, and artificial lights to turn on automatically based on setpoints. Experimental tests and system validation took place in controlled greenhouse conditions. The results show that the system effectively regulates the environment, keeping temperature and humidity within desired limits and optimizing irrigation based on soil moisture. The solar energy system powered the greenhouse automation setup, significantly reducing reliance on grid power and ensuring operation during power outages. Overall, this system offers a cost-effective, reliable, and scalable solution for smart agriculture. It is suitable for small to medium greenhouses and future industrial use. Results indicate improved irrigation accuracy, stable microclimate control, and less manual labor. By providing a reliable and scalable automation framework, this work supports smart farming and adds real value to controlled-environment agriculture.
