Design of Lijiang Water Environment Monitoring System Based on WSN

To solve problems that existed in wired water monitoring system, such as high cost and restricted monitoring water range, a kind of Lijiang River water environment monitoring system is designed based on WSN. In order to ensure long survival time of the sensor node and a high performance of routing node, MSP430 and ARM32F107 processor are employed respectively. After preprocessing data, MU709 3G module will upload them to the remote data management center. Test results show that the system runs stably, its measurements are accurate and reliable, thus the system is suitable for harsh conditions.
