Abstract: Based on a thorough understanding of wireless sensor network， we designed and developed crystal pear growth monitoring system with the modern wireless technology. We proposed CC2430 chips as the core and integral transform PID control algorithm as the main control mode. The system can monitor and regulate air temperature and humidity， soil moisture， light intensity etc， so it can realtime monitor and adjust the crystal pear parameter information or alarming. The system was used in Shanghai Cangqiao crystal pear base， the results showed that the system is superior to the traditional mode of operation in the control of greenhouse temperature and humidity and improving the crystal pear quality rate etc.
