Precision farming, powered by the Internet of Things (IoT), is revolutionising modern agriculture by enabling unprecedented levels of efficiency and productivity. Through the use of smart sensors, GPS technologies, and data analytics, IoT allows farmers to monitor and control various agricultural processes in real time. This targeted approach ensures optimal resource utilisation, such as water, fertilisers, and pesticides, while minimising waste and environmental impact. By leveraging IoT, precision farming enhances crop management through data-driven insights, improving yield forecasting, pest control, and soil health monitoring. This paper explores the key components of IoT-enabled precision farming, highlighting its role in maximizing efficiency, reducing costs, and promoting sustainability. Additionally, it presents case studies of successful implementations, demonstrating how IoT is transforming agriculture into a more precise, adaptive, and environmentally conscious practice.
