Rajamangala University of Technology Srivijaya, Trang Campus, the students from the Faculty of Engineering and Technology, majoring in Computer and Communication Engineering, have developed a smart melon farm system fully managed by Internet of Things (IoT) technology. Melons, particularly the prized “golden melon” variety, require meticulous care, making them highly valued in the market.

The development team, consisting of third-year students, Mr. Sarayut Chukaew, Mr. Sithikorn Jansuksri, and Mr. Patit Ritthong, designed a control system that automates irrigation, fertilization, and temperature adjustment with misting technology. The system, connected to the internet and controlled via mobile devices, promotes optimal growth conditions for melons grown in greenhouse environments while minimizing resource use, especially water consumptions, and environmental impact. By adjusting watering, fertilizing, and temperature to precise levels, the system helps farmers save on water and fertilizer while enhancing product quality. Real-time notifications and scheduled operations also ensure efficient farm management.

The trial crop of 75 Red Honey melon plants yielded 72 melons, each weighing around 3 kg, with a sweet, crisp texture and a pleasant aroma. The melons achieved a high sweetness level of 18 degrees Brix, compared to the typical 14-16 degrees Brix for melons, with a market price of approximately 150 baht per kilogram.

Dr. Phumin Inpan, Head of the Computer and Communication Engineering Department, noted that the smart melon farm project highlights the application of IoT in agriculture. Using sensors to monitor temperature and humidity for automated water and fertilizer distribution reduces the labor required for melon farm management. Farmers can monitor and control farm operations via smartphone, offering convenience and reducing time spent on manual tasks. The closed-system greenhouse trial yielded nearly 100% of the expected production, showing the effectiveness of IoT in transforming traditional farming practices.
