A distributed environment monitoring system based on wireless transparent transmission sensor networks was designed. A 1100E RF chip is taken in this design as a wireless transceiving chip. The data transparent transmission of the pa-rameters in various environments is realized by writing transparent transmission algorithm routine in ATmega128L microproces-sor. Real-time acquisition of parameters in target mornitoring region and various environments was implemented by using RS-232C serial port and PC to communicate. Multi-group data acquired by experiment test are presented. The analysis of the experi-mental data illustrates that this system can achieve real-time monitoring of 254 wireless nodes simultaneously within 400 meters, and the measurement error is about ±0.1% ~±3%.
