Environmental Structure Monitoring
An IoT security monitoring service provider whose operations cover the entire end-to-end process, from independent R&D and design to manufacturing, installation, and maintenance.
The radar water level gauge is a water-level monitoring sensor based on millimeter-wave radar technology. It measures the distance to the liquid surface using high-frequency pulsed waves, delivering millimeter‑level accuracy and robust environmental adaptability.
The device operates reliably under challenging weather conditions such as intense sunlight, rain, fog, and sandstorms. It requires no direct contact with the water body, features simple installation and maintenance, and supports RS485 and 4G communication outputs. It is well suited for automated water-level monitoring in rivers, reservoirs, irrigation districts, and other similar applications.
The geodetic GNSS receiver is a versatile deformation‑monitoring device that integrates a high‑precision GNSS module with MEMS sensors. It supports multi‑system, multi‑frequency signal reception, including BeiDou‑3, GPS, and GLONASS, and delivers millimeter‑level static monitoring as well as centimeter‑level dynamic monitoring.
Equipped with an advanced intelligent fusion algorithm, the device combines satellite positioning data with inertial sensor information to enable continuous, reliable displacement monitoring in complex environments. It is widely applicable to geological hazard and engineering safety monitoring scenarios, such as landslides, subsidence, and mining‑area deformations.
Radar water level gauges are developed based on millimeter-wave radar and designed for measuring water levels.
By recording the time it takes for a pulse wave to travel and multiplying it by the speed of electromagnetic waves, the gauge measures the distance between the liquid surface and the radar antenna, thereby indicating changes in water level. This device is a compact, all‑weather, 24/7 sensor that offers high integration, a small footprint, and easy installation.

Debris Flow Line-Disconnection Monitor
The debris‑flow line‑break monitoring device is an intelligent monitoring and early‑warning system specifically designed for geological hazard prevention in mountainous valleys during flood season. It focuses on real-time sensing and timely reporting of sudden geological hazards such as debris flows and flash floods caused by torrential runoff.
The device integrates high‑precision cable‑strain sensors, data acquisition, and wireless transmission modules, featuring a highly compact and modular design that adapts to complex field conditions. Typically deployed at both ends of debris‑flow‑prone gullies, it employs a physics‑based triggering mechanism to accurately detect the impact and destructive signals generated by debris flows and floodwaters carrying sediment and rocks. This enables second‑level hazard detection, instant data upload, and remote alarm notification, buying valuable time for preemptive evacuation and emergency response.
Array-type displacement sensor
The array-type displacement meter is a flexible, series‑connected three‑dimensional inclinometer array composed of multiple measurement units. It is ideally suited for monitoring three‑dimensional spatial deformations, such as deep‑buried displacements, tunnel convergence, and excavation pit deformation.
