Research and application of the fuzzy control used in the wireless illumination measurement and control system of the greenhouse

Light is an indispensable energy condition for greenhouse crops manufacturing nutrients and keeping life activities, and it is the dominant factor of the greenhouse microclimate. This system give an example about the illumination demands of a common greenhouse crop tomatoes, design a greenhouse illumination wireless observe and control system which based on two dimension fuzzy control algorithm. This paper detailed description the hardware system, the lighting and fill-in light control theory, the design and implementation of the illumination fuzzy controller and its fuzzy control algorithm. The greenhouse illumination automatic control could be easily realized by use of look-up table for the fuzzy inference. Experimental results show that this system is stable and meets the requirements of design.
