Greenhouse control systems are advanced technological solutions designed to optimize the growing conditions within greenhouses, enhancing crop yield, quality, and resource efficiency. By utilizing sensors, actuators, and automation technologies, these systems monitor and regulate environmental parameters such as temperature, humidity, light, and CO₂ levels. This review explores the evolution, current trends, and future potential of greenhouse control systems, highlighting their critical role in sustainable agriculture. The paper discusses various control strategies, from manual to fully automated and AI-driven systems, and examines their strengths, weaknesses, and applications. It also addresses the challenges and future directions for developing more sophisticated and accessible control systems to meet the growing demand for sustainable food production.
