Abstract : This paper introduces a solar-powered, IoT-enabled smart pesticide-spraying system designed for accurate pest management in small-scale environments such as home gardens and greenhouse setups. Traditional sprayers apply chemicals uniformly, which often leads to unnecessary pesticide usage. In contrast, the proposed system minimizes wastage by directing the spray only to areas that genuinely require treatment. An ESP32-CAM module continuously observes plant conditions by capturing leaf images and evaluating them for early indications of disease, nutrient stress, or pest activity. When the system detects an abnormal region, it automatically activates the pump to deliver pesticide precisely to the affected spot. The entire setup is powered through a 10-watt solar panel paired with a 12-volt battery, ensuring uninterrupted operation even in remote or off-grid locations. IoT connectivity allows users to monitor plant health, system status, and spraying activity from a distance, improving convenience and safety. By applying chemicals only when and where needed, the system is capable of cutting pesticide consumption by roughly 30–40%. It also lowers manual effort and reduces human exposure to toxic substances. Overall, this approach efficient, intelligent maintaining plant health and managing pests. By merging automation, renewable energy, and intelligent image-based detection, the system represents a forward-looking solution for modern plant care. It not only enhances plant protection but also encourages responsible pesticide use, making it a valuable tool for both hobbyists and small agricultural operations.
