Abstract：The paper proposed a new method of water quality monitoring by using Zigbee technology，it designed the software and hardware of the sensor nodes in Zigbee wireless sensor network. The coordinator links to the center of water quality monitoring using serial communication RS?鄄232. The center of water quality monitoring utilizes LabVIEW to achieve water information processing，storage and display，and monitors and manages the Zigbee network. The system tests and verifies reliability of sensor nodes collecting and transmitting water information to confirm system function finally.
Key words：Zigbee technology；water monitoring；LabVIEW
