Semi-Plant Factory Artificial Light for Organic Vegetables Using NB-IoT

Plant factory artificial light (PFAL) is a suitable method for growing high-quality plants and increasing crop production to a very high number per area. The major goals of this paper are to implement a NB-IoT based semi-PFAL growing system that use two types of LED array, there are RBLED and phosphor converted LED (pc-LED). Then compare the Cos-lettuce yields under various LED light sources while studying the characteristics of the artificial light spectrum. The semi-PFAL growing system, was controlled for watering, lighting and monitored system operating, temperature and humidity by a NB-IoT module with MAGELLAN platform. The results show that the Cos-lettuce grown under pc-LEDs are probably more capable of photosynthesis than those using RBLEDs. The average fresh weight of the Cos-lettuce from pc-LED significant higher than RB-LED at p<$\theta.\theta$5. The measurement results of environmental parameters, control of lighting and watering in semi-PFAL system, data collected from cloud system under MAGELLAN platform during 20-day of experiment, it was work accurately. The semi-PFAL growing system could be utilized to produce organic vegetables in a home or school setting.
