In order to monitor the water quality change in an expanse,many intelligent sensors need to be distributed. The ideal data summarizing method is wireless data transmission. The characteristics of wireless RF module,GSM module and GPRS module are analyzed and compared. The method to connect these modules to the local MCU is proposed,and the wireless data transmission through these wireless modules is also mentioned. The identification method of the terminal data information in the distributed system is introduced. The distributed water environment monitoring system based on wireless transmission has been put into the test and practice.
