For the characteristics of time consuming, complicated steps and lack of automatic of the traditional water quality monitoring, an automated real-time online water quality monitoring program based on wireless sensor network (WSN) is presented in this paper. This system combined micro-UV-Vis Fiber Optic Spectrometer with ZigBee Wireless Communication Technique to constitute Wireless Sensor Network Node which is placed at the monitoring water,and then used the ZigBee protocol’s real-time transmission and monitor data to raise the automation and monitoring level. This paper discussed the network architecture based on ZigBee protocol, maked design of Optical System of sensor node and the hardware and software and then maked spectroscopy signal real time collection and communication test. The experiment results show that the industrial monitoring system of water quality has few transmission errors, better anti-jamming ability, small size of sensor node, fast inspection speed. All these features are suitable for real-time and continuous monitoring the pollution level of industrial sewage.
