Key Features
3-Axis High-Precision Tilt
Tilt measurement range ±90° with accuracy ≤ ±0.01° and resolution ≤0.001°. Captures minute structural rotations and differential settlements with laboratory-grade precision.
Multi-Parameter Sensing
Simultaneously measures 3-axis acceleration (±2g, ±1mg accuracy), ambient temperature, and humidity-providing a complete picture of structural and environmental conditions in one device.
Dual Wireless Connectivity
4G cellular (Nano-SIM, full network compatibility) for wide-area coverage, plus LoRa self-organizing mesh networking for extended range and redundancy in remote areas.
IP68 Unattended Operation
Rated IP68 (1m water depth, 24-hour continuous test) and operating from -40°C to +85°C. Designed for years of unattended field deployment in the harshest geotechnical environments.
Threshold-Triggered Event Reporting
Configurable angle thresholds trigger immediate data acquisition and upload-e.g., 3° (blue), 6° (orange), 10° (yellow), 15° (red). Captures critical events in real time without continuous high-rate transmission.
>4-Year Battery Life
Powered by a 19,000 mAh primary lithium battery (replaceable) or 6,000 mAh rechargeable pack. Achieves >4 years of operation at a standard 2-hour upload interval, minimizing field maintenance visits.
Product Overview
-
The wireless inclinometer (also known as an IoT wireless tilt sensor or wireless tiltmeter) is an all-in-one intelligent monitoring terminal purpose-built for structural health monitoring (SHM) and geotechnical safety applications. Unlike traditional wired inclinometers that require extensive cabling and data loggers, this device integrates 3-axis tilt sensing, 3-axis vibration acceleration, temperature, humidity, and GNSS positioning into a single compact, IP68-rated enclosure-enabling truly cable-free, unattended deployment in the field.
-
At the core of the system is a high-precision MEMS tilt sensor with ±0.01° accuracy and 0.001° resolution, capable of detecting minute angular changes associated with slope movement, foundation settlement, retaining wall deflection, and structural rotation. A secondary 3-axis accelerometer (±2g range) captures vibration and dynamic motion events, while on-board temperature and humidity sensors provide environmental context for data interpretation.
-
Connectivity is provided through 4G cellular (Nano-SIM, full network compatibility) and LoRa self-organizing mesh networking, with MQTT protocol for cloud platform integration. The device supports both periodic reporting (configurable sampling intervals from 0s to 24h and upload intervals from 0s to 72h, default 2h) and threshold-triggered event reporting-when measured angles exceed user-defined thresholds, the device immediately acquires and transmits data, ensuring that critical events are captured without delay. The companion monitoring platform provides real-time visualization, map-based device distribution, multi-level alarm management, and project health dashboards for centralized fleet management.
