An Intelligent Controlling System for LED Plant Supplemental Lighting Greenhouse

An intelligent controlling system for LED plant supplemental lighting greenhouse is presented in this paper. The key unit of the system is a remote controlling and management center, which comprises of the sensing subsystem, the data acquisition subsystem, the information processing subsystem and the execution subsystem. The combined lighting with red and blue LED was used to provide supplemental lighting for plants in greenhouse. In order to adjust the environment of greenhouse, the controlling system will obtain real-time parameters feedback of the temperature, the relative humidity and the light intensity, and send commands to the execution subsystem through RS-485 communication lines.
