This paper explores the transformative impact of the Internet of Things (IoT) across various sectors, highlighting its potential to enhance efficiency, data-driven decision-making, and connectivity. We examine the core components, historical evolution, and significant applications of IoT, alongside the challenges, future directions, and a study design to assess the impact of IoT on greenhouse farming. The experiment demonstrates its transformative power between the traditional greenhouse management (non-IoT) and a IoT-enabled greenhouse management, comparison of plant growth, yield; analysis of resource consumption efficiency and evaluation of operational costs and labor efficiency. The actual results confirm that IoT technology can have a profound impact on greenhouse farming, leading to better environmental control, enhanced plant growth, higher yields, and more efficient resource management. The findings underscore IoT’s role in revolutionizing industries such as healthcare, agriculture, and manufacturing.
