Abstract: iming at the shortages of long monitoring cycle and limited monitoring scale in traditional water environment monitoring, this paper proposes a water environment monitoring system based on Wireless Sensor Network(WSN), and designs hardware and software system of its wireless gateway. This gateway uses ZigBee and GPRS wireless transmission technology, realizes data bidirectional communication between data monitoring nodes and remote monitoring center. Experimental results show that the system which applies this gateway is stably and reliably, it can well meet the need of remote real time water environment monitoring, it also has wide application prospect.
