For larger waters monitored real-time monitoring capability is not strong, the extent of water pollution monitoring inaccurate problem, build intelligent water pollution monitoring system using ZigBee wireless communication technology and Internet network, water quality testing data sent to the remote water quality monitoring center for aggregation processing, server monitoring center can get the water pollution data for all waters pollution trends, major pollutants. In this paper, water detection sensor module, ZigBee wireless communication module, single-chip peripheral circuits, analog-digital conversion circuits and other hardware design; system software design the contents of the remote parameter settings, drivers, and so on. Through the system test results show that the system for the degree of water pollution detection accuracy rate can reach more than 98%, success rate of communication 100%, water quality testing terminal stable, reliable, real-time monitoring of the communication rate to meet the requirements for a variety of aquatic environment the extent of water pollution monitoring needs.
