Agriculture is essential to humanity's existence. Many methods have been explored to boost agricultural yield. Conversely, bad weather and frequent insect infestations reduce agricultural production. Integrating modern technologies like sensors, The Internet of Things (IoT) brings intelligent farming to agriculture. This uses sensors, technological advances, and data analysis to maximize agricultural yields, resource utilization, and sustainability. This innovative method enables farmers to immediately monitor soil quality, weather, and crop status to make educated choices. Smart farming using IoT technology may improve operational efficiency, food security, and conventional farming practices in a changing agricultural ecosystem. Global studies has shown the need of employing IoT intelligent sensors to monitor moisture, temperature, humidity, and the soil's composition for crop development. Additionally, computerized sensors monitor greenhouse gases including methane, carbon dioxide, and others. Smart farming also monitors soil nitrogen levels, helping farmers estimate fertilizer needs. IoT gadgets like UAVs help monitor agricultural pests and illnesses. Smart farming has drawbacks despite its potential. Big implementation costs, data security concerns, and farmers' lack of digital literacy are the restrictions. If economic tactics, encryption, and technology are used, the IoT might ease smart farming.
