Project Description


Accelerations (X, Y, Z)
Rzsolution: <0,5 mg


3 axes on 360°
Resolution : 0,005°

Temperature (internal or remote)

Range: -25°C to +70°C
Resolution : 0,6°C


Indoor or outdoor
Shock monitoring for buildings, abutments or piles of bridges, dams, engineering structures, earthworks, …
Shock monitoring on rails, catenary poles or pylons

Combined with movements monitoring

Each sensor is autonomous; it doesn’t need another box nor a sending station


IoT, LoRa, LoRaWAN™
High capacity Li-ion cell
10,5cm x 10,5cm x 6cm
Operating temperature: -30°C to +85°C



Autonomous sensor equipped with MEMS probes measuring accelerations and movements with very high accuracy. The threshold triggering allows an early warning of abnormal behavior.

No installation constraints; flexible use with its 3 measuring axes.

Each sensor is autonomous; it does not need another box or a sending station


Monitoring in the fields of railroads, building, bridges, structures, monuments, natural risks or geology.


Measurement axes are clearly identified to ease installation.

Mounting plates

Sensor is delivered with magnetic plate

Il peut également être livré avec des plaques de fixation.
