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 uses high-frequency pulsed waves to measure the distance to the liquid surface, offering 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, is easy to install and maintain, and supports RS485 and 4G 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 determines the distance between the liquid surface and the radar antenna, thereby indicating changes in water level. This device is a compact, all‑weather, all‑time sensor that offers high integration, a small footprint, and easy installation.
Integrated Soil Moisture Monitor
The integrated soil moisture monitor is a multi-layer soil moisture sensing device based on the frequency-domain reflectometry (FDR) principle, capable of simultaneously measuring volumetric water content at three distinct depths within the same soil profile.
The device integrates high-sensitivity sensors, a low-power processor, and a wireless communication module, supporting remote configuration and real-time data transmission. It features robust temperature compensation and excellent soil adaptability, making it well-suited for long-term soil moisture monitoring in precision agriculture, landslide early warning, eco-hydrology, and other applications.
The rainfall monitor is a fully automatic rainfall recording device featuring a dual‑bucket mechanical design, offering a resolution of 0.2 mm and a measurement accuracy of ±2%. It can operate reliably under extreme temperature and vibration conditions.
The device integrates rainfall sensing, data storage, and wireless transmission capabilities, supporting real-time calculation of rainfall intensity and cumulative rainfall statistics. It is widely used in meteorology, hydrology, geological hazard monitoring, and urban flood‑control surveillance.
Integrated Tilt (Collapse) Monitor
The integrated tilt (collapse) monitoring device is an intelligent monitoring system that combines high-precision sensing, wireless transmission, and a high level of environmental protection. It employs triaxial MEMS tilt and vibration‑acceleration sensors to continuously acquire real-time data on structural tilt angles, acceleration, and ambient temperature and humidity, which are then transmitted to a cloud platform via 4G, LoRa, or other communication methods.
This device is ideally suited for long-term safety monitoring of slopes, bridges, towers, and other structures. Featuring low power consumption, extended battery life, and strong anti‑interference capabilities, it provides reliable data to support structural health assessments and disaster early warning.
The Integrated Crack Monitor is an intelligent monitoring terminal that leverages cable‑pull displacement sensing and multi‑parameter fusion technology, specifically designed for monitoring surface deformations such as slope cracks and retaining wall fissures.
The device incorporates a high‑precision displacement sensor and a triaxial accelerometer/tilt sensor, enabling real-time measurement of crack width changes, wall vibrations, and tilt angles. Data can be transmitted remotely and alarms triggered via LoRa or 4G networks.
With a robust structure and straightforward installation, it is well suited for long‑term automated monitoring in harsh outdoor environments.
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 the 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, 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 impact‑induced signals from 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.
The device employs high‑precision MEMS sensors and a flexible circuit design, enabling it to bend freely with structural deformation while providing real‑time outputs of displacement, tilt angle, and vibration data. It also features trigger‑based data acquisition and a low‑power sleep mode, making it well suited for long‑term, concealed‑installation monitoring and automated safety‑alert systems.
The vibrating‑wire piezometer is a pore‑water pressure measurement device based on the vibrating‑wire sensing principle. It is designed for long-term installation in soil, concrete dams, or foundations to monitor seepage pressures and water‑level fluctuations.
The sensor features a stainless‑steel construction and a thermally stable design, offering high accuracy, low drift, and excellent corrosion resistance. When paired with an intelligent data‑acquisition system, it enables remote calibration, fault diagnosis, and seamless integration with cloud platforms, making it widely used in hydraulic engineering, geological hazard monitoring, and geotechnical applications.
Wireless Early-Warning Broadcasting / RTU Data Acquisition Unit
The RTU data acquisition unit is a multifunctional, low-power smart data acquisition and control terminal featuring multiple interfaces and supporting direct connection to various types of sensors.
It integrates 4G and LoRa dual-mode communication along with battery management capabilities, enabling local data processing, anomaly alarms, and remote command issuance. It is well-suited for edge computing and centralized control in distributed monitoring systems.
