Abstract: In modern greenhouse production，precise monitoring and stable control of temperature and humidity are key to achieve efficient production.A wireless intelligent monitoring system for greenhouse temperature and humidity based on wireless microcontroller CC1110 and fuzzy control algorithm was designed.The system composition and its application in greenhouse production were described，hardware and software design and fuzzy control algorithm design process were introduced.Simulation tests for the whole control process were carried out.The result showed that the overshoots of temperature and humidity change were little，control process was stable，this system could meet the control requirements.
