              sensors are a state of the art solution for ambient vibration tests and monitoring and can be set up for temporary or permanent sensing tests. It features:

   •   Highly sensitive triaxial MEMS accelerometers

   •   Highly sensitive triaxial velocimeters

   •   High dynamic range

   •   Low noise levels

   •   Adjustable sampling frequency

   •   Scalable network between 1 and 32 sensors

   •   Synchronisation accuracy for several hours (1 ms)

   •   20 hours of operational battery life

   •   Internal temperature and humidity sensors

   •   Entirely wireless solution with cabled options

   •   Data management on the Amazon Cloud

   •   Operational using the Sensequake Android app

Control your fleet of Sensequake Larzé sensors directly from the palm of your hand!

With the Sensequake app downloaded directly onto your Android smartphone, you can have unlimited control of your Larzé sensors.

From the application you can begin sensing tests, monitor the data collection of your individual units, check the battery levels of your sensors and change the many data collection parameters for your individual tests.

Ambient Vibration Testing

The Larzé ambient sensors have the exactitude and internal power to conduct state of the art ambient vibration analyses. By using the sensors in a mesh and deploying them on your structure's critical points, you can extract the information necessary for an extensive look at your structure. These wireless sensors are controlled via a user-friendly Android application, allowing for very simple and rapid testing.


These analyses allow for the detection of hidden defects, undocumented structural modifications and integrity concerns not detected by visual inspection and traditional engineering practices which can significantly improve disaster preparedness and recovery plans.

The wireless Larzé sensors can be deployed across your structure by staying synchronized for multiple hours

Our sensors bring ease of use to complex ambient vibration tests with IP66 waterproofing, optional GPS and cellular connectivity for precise synchronization as well as up to 32 sensor meshes in order to extract minuscule vibrations from your structure. The data can be easily extracted via micro-USB or pushed directly to our cloud servers.

Periodic Monitoring

Ambient vibration tests can garner even greater results when done periodically. A baseline is made through a first test, which is similar to the DNA or fingerprint of the structure. Additional tests can show any differences in the structure done by damages or the aging of structures.

These periodic tests can be done after any significant events or every few months or years for more important and at-risk structures.

Permanent Monitoring

Our Larzé Vibration System has been developed in-house in order to perform our state of the art ambient vibration test. Once deployed, the sensing test is initiated and monitored by a custom phone application. The data is sent to the cloud for analysis by our team of experts and the results are sent back to you.

Set up monitoring thresholds

Receive notifications on your devices

Once in the cloud, a web portal is used to control the permanent sensor installation. You can configure the sensor network, threshold methods and levels for creating alarms for strong motion events. There you can also schedule period ambient vibration measurements.


Another site can allow users to see the data records both from temporary and permanent systems. You can also create building geometry and assign sensor nodes based on your data.


We are currently working on a dashboard for the results, events and alarms as well as adding more data analytics.

Vibration Monitoring

With the Larzé cloud system, vibrations of nearby construction projects or specialized machinery and equipment can be monitored in real time. Thresholds can be set to send real-time notifications once limit vibrational levels have been exceeded.

Close monitoring of excessive vibrations is often an important step in large construction or excavation projects in order to protect surrounding structures and their foundations.
