Abstract Agriculture is a key sector that supports the econ- omy and ensures food security, particularly in developing coun- tries where many people depend on farming for their livelihood. However, traditional farming methods are still widely practiced and mainly depend on manual observation and farmers’ expe- rience. This often leads to inefficiencies and challenges, such as unpredictable weather conditions, poor irrigation practices, soil degradation, and plant diseases. As a result, farmers frequently face reduced crop yields and financial losses. To overcome these challenges, modern technologies like the Internet of Things (IoT) and Artificial Intelligence (AI) are being introduced into agriculture. This project presents a Smart Agriculture System that integrates IoT and AI to improve farming efficiency and productivity. The system uses IoT sensors installed in fields to continuously monitor key environmental factors such as soil moisture, temperature, and humidity. The collected data is transmitted to a cloud platform, where it is stored and analyzed in real time. AI algorithms process this data to evaluate soil conditions and seasonal patterns, helping farmers select the most suitable crops for cultivation. In addition, an AI-based image processing system detects plant diseases from crop images and provides recommendations for appropriate fertilizers and pesticides. This helps in early detection and prevention of crop damage. A user-friendly mobile application allows farmers to access real-time data, receive crop suggestions, get disease alerts, and learn about government schemes. Overall, this system reduces manual effort, improves resource management, increases pro- ductivity, and promotes sustainable farming practices.
