Abstract：Aiming at the shortcomings existing in traditional mobile measurement and control system，such as real-time problem and high cost，a multifunctional wireless measurement and control system based on ZigBee and GPRS was designed combining the ZigBee and GPRS technology. The system is compose of sensor node with local measurement and control function，router and coordinator. In the sensor node MC56F8037 was adopted for measurement and control，JN5139 was adopted for ZigBee communication，and series communication was used to exchange data between two components. The coordinator is composed of JN5139，CP2200 and SIM900A

module. The multi-interface was implemented in the coordinator besides management of ZiBee network with embedded Ethernet protocol，GPRS protocol and TCP/IP protocol for control based on Internet. The results indicate that the system provides the practical and effective solution for remote monitoring and control with low price and broad market prospects.
