DHT Subsurface Data Terminal
The DHT Subsurface Data Terminal integrates digital sensors such as Doppler flowmeters and UV-based organic analyzers to continuously monitor subsurface hydrological parameters (e.g., flow velocity, water level) and water quality indicators (e.g., COD, ammonia nitrogen). Leveraging modern sensor technology, IoT connectivity, cloud computing, and low-power design, it forms an intelligent online monitoring system for real-time data acquisition and analysis.
