Wireless SHM accelerometer
The Move SHM accelerometer can measure the acceleration of the point where it is installed, in three axes, with high resolution. All these SHM Accelerometers can be perfectly synchronized with each other. Thanks to this feature, it is possible to measure Vibration Frequencies and perform a Modal Analysis of the structure.
SHM Move Solutions Accelerometer
This device is the next and updated version of the Triaxial Acceleration Monitoring sensor. It is the SHM Accelerometer, an extremely precise three-axis wireless sensor, capable of synchronizing data samples with all other SHM Accelerometers in the system. Wireless synchronized sampling is a very important feature that brings many advantages during structural monitoring. Thanks to this feature, it is possible to perform Modal and Vibrational Analysis of any type of structure. Sampling rates are variable and remotely configurable. The SHM Accelerometer also maintains the classic activation threshold operation. The battery-powered device has an operating life of up to 8 years and also includes a temperature sensor.
The wireless SHM Accelerometers transmit precise readings from the site via the LoRaWAN wireless communication protocol through a gateway. You can view and interact with your data online through the Move Cloud platform.
Like other devices, it is fully wireless, and the battery lasts for years, depending on the transmission frequency (timed and/or threshold crossing). The SHM Accelerometer also integrates a temperature sensor inside.

Easy installation of the Move wireless monitoring system
The installation of an entire wireless sensor system on-site is quick and easy: simply mount each device with at least two screws on the structure you want to monitor and power the LoRaWAN gateway. You can configure the entire system remotely, before, during, or after installation, using your laptop or tablet. After mounting and configuration, the Move wireless monitoring system will start measuring and you can begin remote monitoring.
Operation of the Move wireless monitoring system
The wireless sensor system automatically communicates measurement data via LoRaWAN with the on-site gateway, which in turn sends the received data via 4G or LTE to online servers. The Move Cloud Platform is the cloud-based web tool that allows you to access, view, and export your measurement data and configure the settings of the entire sensor system. You can access the Move Cloud Platform 24/7 from anywhere or any device in the world. One of the main advantages of the Move Cloud Platform is that it offers remote access to measurement data and allows the remote configuration of all installed sensors. This saves time and labor. Additionally, you can analyze measurement data using processing algorithms included in the service. Perform calculations, correlations, and complex analyses automatically and effortlessly. With just a click, you can export measurement data in CSV format. You can also easily set up alerts to multiple recipients who will receive threshold crossing notifications via email.
- Easily install the entire system on the structure without wiring.
- Quickly and remotely configure all wireless sensors.
- View measurement data in real-time wherever you are, on any device, 24/7.
- Process collected data using the implemented algorithms.
- Constantly monitor the operational status and signal quality of the system remotely.
- Customize alarm notifications and receive overload notifications via email.
- Optionally, you can integrate the data into your platform via an MQTT bridge, FTP, or API calls.
