Severe drought conditions in Thailand, particularly in highland areas with limited water access, have significantly impacted durian cultivation in Nakhon Thai District, Phitsanulok Province. This study develops a smart irrigation system for highland durian seedlings by integrating fog harvesting technology and atmospheric water generation (AWG) via an Internet of Things (IoT) framework. The system consists of a fog collector using 0.8 mm nylon mesh and a condensation–based AWG unit, managed by an ESP8266 microcontroller with cloud-based data logging and solar power integration. A 90–day field experiment on Monthong durian seedlings demonstrated that the system produced an average of 0.7 L/day from fog harvesting and 1.2 L/day from AWG, totaling 1.9 L/day. This output was sufficient to sustain the growth of one–year–old seedlings, achieving a 100% survival rate throughout the trial period with a low energy consumption of 0.3 kWh/day. The results confirm that this integrated IoT–based architecture provides a sustainable and efficient water management solution for remote and drought–prone agricultural regions. © 2026, King Mongkut's Institute of Technology Ladkrabang.
