The integration of the Internet of Things (IoT) in agriculture has emerged as a transformative force, revolutionising traditional farming practices through sensor data fusion. This research explores the potential of sensor data fusion in optimising agricultural processes. By deploying a network of diverse IoT sensors across the agricultural landscape, it enables the comprehensive collection of real-time data on environmental conditions, soil quality, crop health and livestock monitoring. The research assesses the performance of the IoT sensor data fusion system through field trials, comparing it to traditional methods. As IoT sensor data fusion continues to evolve, its scalability and cost-effectiveness open doors for widespread adoption, promising a more resilient and data-driven future for farming.
