Atmospheric Water Harvesting (AWH) has emerged as a sustainable solution to address global water scarcity by extracting potable water directly from humid ambient air. This paper presents the design and experimental evaluation of a smart atmospheric water harvesting system powered by renewable energy sources such as solar or wind energy. The proposed system employs thermoelectric (Peltier) cooling and vapor condensation principles to convert atmospheric moisture into liquid water, followed by multi-stage purification including sediment filtration, activated carbon filtering, and ultraviolet sterilization. To enhance automation and operational efficiency, image processing techniques are integrated for realtime monitoring of condensation behavior, water generation rate, and storage tank levels. The closedloop intelligent control reduces energy consumption, improves reliability, and minimizes manual supervision. Experimental results demonstrate effective water production under varying humidity and temperature conditions, confirming the feasibility of decentralized potable water generation for rural, remote, and disaster-affected regions. The system offers a compact, eco-friendly, and cost-effective approach for sustainable water supply infrastructure.
