IoT-Enabled Monitoring Equipment for Flash Floods and Geohazards Ensures Precise, Comprehensive Surveillance

Leveraging IoT technology, this monitoring system integrates multi-dimensional terminals—such as sensors for rainfall, water level, displacement, and ground cracks—to capture critical hazard data around the clock. Data is transmitted wirelessly to a central monitoring platform, providing a reliable foundation for early warning and prevention strategies against flash floods, landslides, and debris flows.

This equipment serves as a core hardware component of modern flood and geohazard prevention systems. Built on an IoT architecture, it integrates specialized monitoring terminals with supporting power supply and transmission units to create a comprehensive, continuous field monitoring network. The core system comprises stainless-steel rain gauges, data loggers, solar power systems, and mounting poles. It can also be configured with additional devices—such as displacement meters, crack monitors, mud-level sensors, and GNSS positioning units—to meet the specific needs of various geohazard scenarios. Designed for stability and ease of maintenance, the system is fully adapted to harsh, complex field environments.

The equipment features robust data acquisition and transmission capabilities, accurately capturing metrics such as rainfall status, interval rainfall, and cumulative rainfall (daily, weekly, monthly, and yearly), alongside real-time parameters like water levels, soil displacement, mountain fissures, and debris flow volume. All data is wirelessly transmitted to the IoT monitoring platform in real time. Personnel can access live data and historical records via the platform, which supports one-click export to Excel. This facilitates data analysis, risk assessment, and record-keeping, providing a quantitative basis for effective hazard prevention and control.
