Abstract: Aiming at the problem of environmental monitoring in real-time remote data collection, transmission, remote control and analysis, the Zigl3ee protocol and RF communication on principle are discussed. Through GPRS technology, the remote monitoring of real-time wireless data transmission is achieved. Based on the ARM chip S3C2440 as the core the hardware circuits are designed, in the embedded Linux developed monitor application and the PC software in the VS2005 development. Through MC35i module, communication of GPRS network and Internet monitoring center is a- chieved, so as to provide a good platform for the overall monitoring of the urban environment.

Key words: ZigBee protocol, RF communication, GPRS, Embedded
