Abstract
Nowadays, irrigation accounts for almost 70% of global water usage. Therefore, it is essential to design irrigation systems in such a way that it can reduce water usage as well as the expense. Making eco-friendly irrigation systems is another challenge for researchers. To overcome these problems, a variety of appliances and systems combining state-of-the-art software and hardware features have been developed. Yet, research on smart irrigation systems is ongoing. To have a comprehensive understanding of the prospective and continuing instance, this study presents an overview of recent advancements in smart irrigation systems. A variety of irrigation system designs are addressed, including solar-powered, Wireless Sensor Network (WSN)-based, and Internet of Things (IoT)-based systems. The authors firmly expect that this research will significantly influence the most recent developments in smart irrigation systems.
