Water quality monitoring have played an important part in the work of the water pollution prevention and water environment protection. However, at present, in our country, the water environmental monitoring in the practical work, using a large number of monitoring methods which can not satisfy the environmental protection, cause of the evolving needs of the community, so the study of water quality monitoring system, the development of water quality monitoring technology is very important now. This paper based on water quality monitoring system to carry on the preliminary study, discussed the project research background, domestic and international current situation of the development of water quality monitoring system. At last we will take AT89C51single-chip microcomputer as main control device, using a glass electrode sensor, designed a water pH monitor.
