Development of Wireless Sensor Networks (WSNs) for Water Quality Monitoring

Sustainable water resource management decisions are made on the support of real time water quality monitoring data at fine temporal and spatial granularities. Recently, development of wireless sensor networks (WSNs) indicates a great potential to revolutionize water quality data measurements. In this paper, based on our existing work, we report our progress to collect water parameters through utilizing STORM3 from YSI, a WSN from National Instruments (NI), and eKo Pro Environmental Monitoring System from Memsic. Their prototypes have been deployed in the pond at Lamar University in Beaumont, TX. Two H-377 water temperature sensor probes from WaterLOG have been integrated with STORM 3, the 15-minute interval water temperature data have been collected since October 1, 2015. Two sensors provided the consistent sediment temperature data for one year. To provide better hydrodynamic analysis, two sensors have been deployed at two different depths and continue to provide good data. The on-going research to develop hydrodynamic model to predict the water temperature by utilizing the data from WSNs.
