Rugged IoT Sensors & Data Loggers for Infrastructure Monitoring
Long-range, low-power wireless edge devices engineered for continuous structural health monitoring across bridges, tunnels, dams and industrial facilities — field-ready, IP68-rated, and built to last decades.
Benefits Built for the Field
Engineered for unattended long-term deployment in the harshest environments — from underground tunnels to exposed bridges — with minimal maintenance and maximum uptime.
High Scalability
Easily expand your monitoring system as your project grows. A single network supports hundreds of wireless devices reliably and securely.
devices into a single network
Industry-leading battery lifespan
High-energy, user-replaceable C and D cell batteries keep your edge devices operating for decades without revisiting remote deployment sites. Solar-assisted options available for zero-touch deployments.
Low Maintenance
Minimize on-site visits. The Sentra edge devices are built for autonomous long-term operation, drastically reducing lifecycle maintenance costs.
Rapid Deployment
Wireless design and a mobile setup app means your team is up and running on-site within hours, not days.
Expert Support
Our IoT monitoring specialists are available to guide deployment, configuration and troubleshooting for every project.
Easy Troubleshooting
Integrated diagnostic tools, offline radio coverage testing, and real-time alerts make issue detection fast and field-friendly.
What Makes Our Edge Devices Different
Purpose-built for unattended infrastructure monitoring with a hardware-software stack designed for reliability at the edge.
Superior Wireless Connectivity
LoRaWAN long-range communications up to 15 km with support for 4G LTE, Bluetooth and RS-485 fallback. Operates on dedicated networks without internet dependency.
Durable, IP68-Rated Hardware
Industrial-grade enclosures rated IP68 for full submersion resistance. Operates reliably from −40°C to +85°C — from Arctic cold to desert heat.

Mobile App Configuration
Configure devices in the field via the Sentra mobile app. Built-in setup wizard, radio signal coverage testing, and data sampling — no laptop needed.
Cloud & SCADA Integration
Transmits data securely to cloud platforms for real-time dashboards, historical analysis, and automated alerting. BIM and GIS integration ready.
Configurable Reporting Intervals
Set reporting periods from 30 seconds to 24 hours based on project needs. Triggered event detection for seismic, tilt or vibration anomalies.
Where Our Edge Devices Deploy
Sentra edge devices are designed for large-scale, unattended monitoring across surface and underground environments.
Bridge Monitoring
Continuous vibration, tilt and deflection monitoring on road and rail bridges for structural health assessment.
Building & High-Rise
Track settlement, tilt and seismic response in real time during construction and throughout service life.
Dam & Reservoir
Automated piezometer, tiltmeter and GNSS networks for early warning and seepage detection on embankment dams.
Tunnels & Metro
Underground sensor networks for convergence, vibration and groundwater monitoring in tunnelling projects.
Geotechnical Slopes
Landslide and slope stability monitoring with inclinometers, tiltmeters and rainfall sensors on remote terrain.
Industrial Infrastructure
Pump houses, tanks, silos and industrial facilities where predictive maintenance and vibration data drive uptime.

Sentra edge devices are suitable for bridges, buildings, tunnels, dams, industrial facilities, wind turbines, slopes, retaining walls and any structure where continuous vibration, tilt or deformation monitoring is critical for safety and performance.
Devices use high-energy C or D cell batteries with up to 25 years of field life depending on reporting interval. Batteries are user-replaceable without tools. AC/DC power input and solar panel integration options are also available for continuous or solar-powered deployments.
Our devices support LoRaWAN for long-range wireless communication (up to 15 km), 4G LTE for cellular connectivity, Bluetooth for local mobile app configuration, and RS-485 for wired integration with existing SCADA or data acquisition systems.
Yes. All devices are rated IP68 for full submersion protection and carry industrial-grade certification. Operating temperature range is −40°C to +85°C, making them suitable for underground mines, coastal bridges, mountain slopes and tropical environments.
Data is transmitted to Sentra's cloud platform and accessible via web dashboards or mobile apps. The platform includes real-time visualisation, historical trend analysis, automated threshold alerts, and export integrations for BIM and GIS platforms.
A single Sentra LoRaWAN gateway network can support 1000+ wireless sensors and data loggers simultaneously — ideal for large-scale infrastructure projects like dam instrumentation networks or city-wide bridge monitoring programmes.
