SENCEIVE - Optical laser distance sensor
Triaxial Tilt Sensor Node with optical distance measurement.
The measurement data is transmitted to a gateway via Senceive's wireless communication network.
The distance measurement provides information about the 1D deformation of a target structure and the tilt measurement informs the user about the stability of the sensor itself as well as the reference structure where the sensor is located.
Optical deformation measurement is ideal for many structural and geotechnical monitoring applications:

Optical deformation measurement is ideal for many structural and geotechnical monitoring applications:
- Convergence/divergence for tunnel/arch inner walls or bridge abutments
- Vertical movements for structural settlement/lifting
- Lateral movements, such as the pivoting of tracks
- Earthworks and embankment movements
- Water level monitoring/drainage
Features:
- 3-axis MEMS sensor with optical distance measurement and internal temperature sensor
- Extremely low-noise behavior “High G” version available (vibration-resistant, e.g. in track areas)
