Abstract
This paper describes the development of a wireless sensor network for remote water vapor detection. The network is composed of three parts: the base station, the router node, and the end node. The end node is fabricated from distributed-feed-back (DFB) laser water vapor detection systems. Multi-node topology is adopted among the water vapor detection nodes with ZigBee multi-hop mesh routing protocol for communication, and acquisition data are transmitted to the data center through wireless communication. The network can detect water vapor down to 1 ppm, and an excellent stability is observed in 100 days. The system has been put into an actual test application, and it will be used to monitor environment change with a high precision.
