A kind of imitated environment system for plant growth based on LED light source

Along with the continuous development of LED technology, LED light source gets more attention in the field of research of plant cultivation because of its small volume, long lifetime, good spectrum property, high luminous energy utilization, adjustable light quality and intensity and so on. According to the demand of plant growth environment, the paper designed a kind of imitated environmental system for plant growth based on LED light source. The system with the core of ATmega128L micro-controller, collocate with LED board, humiture sensor and CO₂ sensor and so on, could imitate natural temperature, humidity and illumination etc., and adjust all kinds of parameters to set various combination ecotope to fit plant growth. After actual application, it works well.
