According to the requirement of dam safety monitoring

a CC2430-based wireless sensor networks（WSNs） for the dam safety monitoring system is proposed

integrated with the characteristics of dam safety monitoring sensor networks and Zig Bee technology.The sensor networks architecture is briefly introduced

the design of hardware and software of WSNs are explained.A cluster-tree-typed sensor networks are built in the laboratory environment to test sensor networks and to calibrate the nodes.Experimental results indicate that the sensor nodes collect the data accurately

the data transmission is reliable and accurate

and data loss rate is 0.
