Structural monitoring
IoT structural health monitoring for bridges, tunnels and buildings
See how structures move and age. Wireless sensors measure tilt, vibration, strain, cracks and displacement, and Sensor-Online turns the readings into trends and alerts, so you can act on change instead of finding it at the next inspection.

How it works
From structure to decision.
Install sensors
Tilt, crack, strain, vibration and distance sensors on the structure.
Connect
Battery-powered wireless nodes send data without cables, also from remote or underground sites.
See
Trends and thresholds show how each point behaves over time.
Act
Alerts and reports tell the right people when something changes.
What you can monitor
Typical measurements for structures and construction.
Tilt and rotation
Tilt sensors on bridge piers, walls, buildings and dams.
Cracks and joints
Crack and joint meters show whether openings change over time.
Strain and load
Vibrating-wire strain gauges and load cells for structural elements.
Vibration
Accelerometers and vibration sensors for dynamic behaviour.
Displacement and distance
Laser distance sensors for settlement and movement.
Environment
Temperature, weather and ground conditions around the structure.

Manual readings or continuous monitoring?
What changes when the readings come by themselves.
| Manual readings | Wireless monitoring | |
|---|---|---|
| How often | At each site visit | Continuously, at the interval you choose |
| Access | Someone has to get to the sensor | Data arrives without visiting the point |
| Reaction | Change is found at the next round | Alerts when readings cross your limits |
What the platform does
Tools for owners, contractors and consultants.
Trends and thresholds
Time-series graphs and alarm limits for every measuring point.
Early warning
Alerts by e-mail, SMS, Telegram, webhook or MQTT.
Combine readings
Use the rule engine to look at several signals together, for example tilt and rainfall.
Many sites
Keep projects and customers apart in one multi-tenant platform.
Reports
Export results as PDF, Excel or CSV.
Your own servers
Install Sensor-Online on-premise, with access only to your intranet if you need it.
Monitoring supports engineering judgement
Data does not replace inspections.
Sensor-Online shows the data and sends the alerts. Alarm limits and risk assessment remain the work of qualified engineers.

What is structural health monitoring?
It means measuring how a structure behaves over time, for example tilt, strain, cracks and vibration, to detect change early and support maintenance decisions.
Which sensors are used?
Tilt sensors, crack and joint meters, strain gauges, load cells, accelerometers and laser distance sensors, connected through wireless nodes.
Do I need cables?
No. Wireless, battery-powered nodes send the readings, which makes installation faster and works well in places that are hard to reach.
How do I get alerts?
Set alarm limits and receive alerts by e-mail, SMS, Telegram, webhook or MQTT.
Who decides the alarm limits?
You and your engineers. Sensor-Online shows the data and sends the alerts, while limits and risk assessment remain the work of qualified engineers.
Can it run on our own servers?
Yes. Install Sensor-Online on-premise, with access only to your intranet if you need it.
