The major method of water quality monitoring was sampling in the scene at present in China. In response to the problems such as weak sampling capability of water quality, untimely data processing and so on, based on GPRS technology, the design scheme of an automatic water quality monitoring system is proposed. The system utilizes the water quality monitor to process the sample and send the relevant data to the monitoring center through the GPRS data transmission. Ultimately, the system realized the function of remote collection, transmission and procession of the water quality parameters
