Vibration sensor SHAKEdot
The SHAKEdot measures vibration on three axes directly at the structure and transmits it without cabling and without a construction power supply. It runs self-sufficiently for up to six months and reports a threshold breach the moment it occurs.
- 3-axis MEMS sensor
- LTE-M & NB-IoT
- Up to 6 months self-sufficient
Why the SHAKEdot
Measuring where no cable reaches
Classic measuring systems need cabling, a power supply and configuration on site. The SHAKEdot brings both with it and can be placed where the vibration arrives, not where a cable happens to run.
No cabling
Transmission runs entirely wirelessly via LTE-M and NB-IoT. Even third-party neighbouring buildings can be included without any structural intervention.
Self-sufficient operation
No external power supply needed. The battery lasts up to six months, so the sensor survives an entire construction phase.
Fast installation
Plug and play, without elaborate configuration on site. The sensor is ready to use as soon as it is in place.
Remote access
Measured values and status information are retrievable remotely at any time. No one needs to drive to the site for a look.
Event-based measurement
The sensor records when something happens, instead of filling a continuous curve. This saves battery and data volume and keeps the analysis lean.
Assessed to standards
The characteristic values follow DIN 4150-3 and BS 7385-2 for the structure and ISO 2631-2 for people inside the building.

Operating principle
From piling blow to notification
The sensor sits on the component and waits. Only when a vibration exceeds the recording threshold does it record the event on all three axes. The characteristic values required by the standards are formed from the event and checked against the threshold for the specific building.
- 01
Capturing the event
The 3-axis MEMS sensor samples at 250 Hz and records as soon as the threshold is exceeded. Between events it stays in standby.
- 02
Forming characteristic values
The maximum peak particle velocity is derived as PPV from the three axes. For the effect on people in the building, the MTVV per ISO 2631-2 is added.
- 03
Transmitting and alerting
The values go via LTE-M or NB-IoT into the platform. If the project-specific threshold is exceeded, alerting triggers automatically, by email, SMS or interface.
Simulation
Three axes, one value
A vibration has a direction. The sensor therefore measures on all three spatial axes and derives the maximum peak particle velocity, the PPV. Trigger a piling blow and see which axis carries it.

From the monitoring concept to alerting
The sensor is one building block, not an end in itself. On request, Infrasolute takes care of concept, installation, operation and ongoing monitoring as a complete solution, not separate parts.

The sensor as part of a solution
Whether construction-phase over weeks or permanent over years, the device is the same, the question decides the concept.
Construction vibration monitoring (DIN 4150)
The construction-phase application: thresholds by building class, condition surveys and automatic alerting for piling, demolition and blasting.
View solution Vibration monitoring
The long-term application: peak particle velocity and natural frequency tracked over years, with trend analysis and alerting on deviation.
