In the field of precision farming, IOT has played an essential role in revolutionizing the whole agricultural system. It not only just increases the yield and economic status of the farmer but also helps in the sustainable farming practices. It helps in different areas of agricultural practices like smart irrigation, fertilizer application by the help of drones, soil mapping etc. By integration of artificial intelligence (AI) with the Internet of things (IoT), the whole agricultural system has become more efficient, convenient and sustainable. In the conventional farming method, the farmer has to frequently visit his field throughout the crop-growing season to monitor his crop. Farmers spend most of their time analyzing and monitoring crop conditions rather than working in the field, which makes smart agriculture necessary. Beyond agronomic improvements, the Internet of Things is revolutionizing agriculture and providing real financial gains for farmers. Farmers may optimize the distribution of resources, boost profitability, and achieve notable yield increases by utilizing big data analytics and IoT-driven insights.
