Agriculture remains the backbone of food security and economic stability, yet crop losses due to plant diseases continue to pose a significant global challenge, reducing annual yields by 10% to 40%. Traditional monitoring relies heavily on manual field scouting, which is labor-intensive, subjective, and often too late for effective target intervention, leading to excessive chemical usage. This research paper presents an integrated automated edge solution combining computer vision, deep learning, and robotic precision spraying mechanisms. Deployed on a resource-constrained Raspberry Pi 3 platform, a trained lightweight YOLOv8-Nano model processes real-time leaf images captured via a high-resolution camera module to identify fungal, bacterial, and viral infections. Upon disease confirmation with a confidence score exceeding 0.90, the synchronized on-board system triggers a multi-channel relay array and high-speed solenoid valves, delivering localized pesticide doses tailored to affected foliage sections. Empirical validation confirms a disease classification accuracy of 97.5% on the test dataset and a dramatic 75% reduction in chemical consumption compared to traditional broadcast methods, showcasing an affordable and ecologically sustainable approach toward precision smart farming.
