Sensors, IoT and observation networks
Sensors, IoT and observation networks collect continuous measurements of physical, environmental and operational conditions. They provide the real-time inputs that early warning and asset monitoring depend upon. Critical Infrastructure stewards this page for the Nexus Consortium.

The short answer.
Sensors, IoT and observation networks collect continuous measurements of physical, environmental and operational conditions. Observation networks enable early warning and condition-based maintenance. In the Nexus Consortium, Critical Infrastructure stewards its canonical page, and 3 other platforms apply it, including Water Nexus as well as Cities and Built Environment.
Systemic exposure in Indonesia.
Where people and networks concentrate, the exposure through which shocks travel between systems, shown for Indonesia as an example geography for this subject.
What sensors, IoT and observation networks covers.
- 01
Core methods
sensor network design; edge data processing; calibration and drift correction; anomaly detection; data fusion; telemetry management.
- 02
Data and instruments
environmental monitoring stations; structural health sensors; smart meters; low-cost air quality sensors; industrial control telemetry.
- 03
Validation
Sensors are calibrated against reference instruments and checked through co-location and redundancy. Data quality flags and automated range checks catch faults.
- 04
Limits
Sensor drift, power loss and connectivity gaps degrade data during the events of most interest. Dense networks raise security and privacy concerns.
- 05
Use in risk decisions
Observation networks enable early warning and condition-based maintenance. They reveal how stresses in one system appear in connected systems in near real time.
Sensor networks follow WMO observing standards and device security baselines.

| IEC 62443 | Security of connected industrial devices |
| OGC SensorThings API | Interoperable access to sensor data |
Dense data, uneven quality.
Low-cost sensors and connected devices can fill observation gaps in cities, rivers and infrastructure. Their value depends on calibration, maintenance and metadata, all of which decay without funding. Connected sensors in critical systems are also an attack surface.
- Record calibration history and drift.
- Flag gaps from device failure distinctly from true zero values.
- Assess the security of sensors embedded in control systems.

Terms used on this page.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Telemetry | Automatic transmission of readings from remote instruments to a central system, by radio, cellular or satellite link. |
| Rating curve | The relation between water level and discharge at a gauging station, used to convert continuous level readings into flow. |
| Sensor drift | A gradual change in an instrument's readings unrelated to the quantity measured, corrected by regular calibration against reference measurements. |
| Structural health monitoring | Using sensors to detect damage or deterioration in structures over time. |
