Leveraging Internet-of-Things (IoT) technologies, the data acquisition system delivers powerful capabilities for efficient and accurate monitoring and analysis of hydrological data, including water levels, sediment levels, and meteorological parameters. Paired with NEXCOM Smart Staff Gauge, it enables near real-time EC profile data collection and transmission at multiple depths in specific locations within a water body. These EC variations, combined with concurrent water-level changes, provide early and reliable indicators of river dynamics.
