BWSENSING LoRaWAN Inclinometer LWHD-WM400 deployed for bridge tilt monitoring in Brazil.

Project Overview

Brazil has been continuously investing in transportation infrastructure, including bridges, elevated roads, tunnels, and urban mobility projects. During bridge construction, structural components may experience slight inclination or displacement due to loading, concrete curing, foundation settlement, vibration, or environmental factors. If these changes are not detected in time, they may affect construction safety, structural stability, and long-term service performance.

In an elevated bridge construction project in Brazil, Braspowertech, a leading local IoT integrator, selected the BWSENSING LoRaWAN Inclinometer LWHD-WM400 for real-time tilt monitoring. The sensor was deployed on key structural positions of the bridge to continuously capture subtle angular changes and transmit high-accuracy inclination data wirelessly to the monitoring platform.

With reliable wireless communication, stable data output, and high-precision tilt measurement, the LWHD-WM400 enabled the project team to detect even slight inclination trends at an early stage. This gave engineers more dependable data for structural assessment, construction adjustment, and overall safety management throughout the project.

Industry Challenges in Bridge Tilt Monitoring

Bridge construction monitoring requires continuous and accurate data collection under demanding field conditions. Traditional wired monitoring solutions may face limitations in installation efficiency, maintenance cost, and data transmission coverage, especially in large-scale construction sites.

1. Difficult Cable Deployment

Elevated bridge sites often have complex structures, wide monitoring areas, and frequent construction activities. Laying cables across the site can be time-consuming, costly, and vulnerable to damage during construction.

2. Need for High-Accuracy Tilt Data in Real Time

Bridge components may experience very small tilt changes caused by load variation, support adjustment, temperature fluctuation, or foundation movement. For engineering teams, the challenge is not only to monitor in real time, but also to obtain sufficiently accurate inclination data to distinguish meaningful structural change from normal environmental disturbance and support timely decision-making.

3. Harsh Outdoor Environment

Monitoring equipment must operate reliably under outdoor conditions such as rain, dust, vibration, humidity, and temperature changes. Stable sensor performance is essential for long-term project safety.

4. High Maintenance Cost

For bridge and infrastructure projects, frequent on-site maintenance can increase labor cost and affect construction efficiency. Low-power wireless devices can reduce maintenance frequency and improve monitoring continuity.

BWSENSING Solution

To address these challenges, BWSENSING provided the LoRaWAN Inclinometer LWHD-WM400, a wireless tilt monitoring sensor designed for structural health monitoring applications where measurement accuracy is critical. The device combines high-precision inclination sensing with LoRaWAN wireless communication, allowing customers to obtain reliable tilt data from dispersed monitoring points without complex wiring.

Installed at critical positions of the elevated bridge structure, the LWHD-WM400 continuously measured tilt changes and transmitted accurate, stable data to the client’s IoT monitoring platform. This enabled the project team to track subtle inclination trends over time, evaluate structural behavior with greater confidence, and respond more quickly to potential safety risks.

The sensor can be integrated into IoT monitoring platforms through LoRaWAN gateways, enabling data visualization, trend analysis, alarm settings, and remote monitoring.

How the Monitoring System Works

Step 1: Sensor Installation

LWHD-WM400 sensors are installed on selected bridge structural points where tilt changes need to be monitored.

Step 2: Data Collection

The sensors continuously measure inclination data and record structural tilt changes during construction.

Step 3: Wireless Transmission

Monitoring data is transmitted wirelessly via LoRaWAN to the gateway and then uploaded to the cloud or local monitoring platform.

Step 4: Data Analysis and Alarm

Engineers can monitor real-time tilt trends, set alarm thresholds, and make timely decisions based on accurate structural data.
