This paper presents an illumination control system for horticulture based on wireless sensor network. In this research, we want to design and control light-emitting diode (LED) lighting system by using buck converter circuit and microcontroller for red and blue LED. The wireless data are sent to the network by Zigbee wireless sensor for monitoring, controlling and processing at faraway places. The result shows that this research can control the illumination of LED for plant photosynthesis, and users can access real time data via the precise wireless network. Furthermore, this research can reduce the electricity consumption by more than 35% as compared to T5 fluorescent lamp.
