Wireless Sensor System


Wireless Accelerometer

Move Solutions Accelerometer is a wireless sensor that measures acceleration and frequency on three axes. It can be synchronised with other Accelerometers for Modal Analysis and it detects seismic vibrations. The device can be set up and managed remotely via Move Solutions IoT Platform.


Bridge Monitoring

Monitor all the dynamic parameter of a bridge as frequency, modal shape and damping using our synchronized accelerometer.

Dam Monitoring

Monitors the strong vibrations caused by the pressure and flow of water against the structure.

Building Monitoring

Monitor all the accelerations of the building given by environmental causes or constructions. Use our tools to perform modal analysis

Move Solutions Accelerometer is an extremely precise three-axis wireless sensor, capable of synchronizing data samples with all the other Accelerometers in the system. Wireless synchronized sampling is a very important feature that gives many benefits during structural monitoring. Thanks to this feature it is possible to carry out the Modal and Vibrational Analysis of any type of structure. Sample rates are variable and remotely configurable. The Accelerometer also maintains the classic activation threshold operation. The battery-powered device has an operating autonomy of up to 8 years and it also has a temperature sensor.

The wireless Accelerometers transmit accurate readings from the site via the LoRaWAN wireless communication protocol via a gateway. You can view and interact with your data online using Move Solutions IoT Platform.

Easy installation of Move Solutions 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 assembly and setup, the Move Solutions wireless monitoring system will start measuring and you can start monitoring remotely.

Operation of Move Solutions wireless monitoring system
The wireless sensor system automatically communicates the measurement data via LoRaWAN with the on-site Gateway which in turn sends the received data via 4G or LTE to the online servers. The Move Solutions IoT 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 Solutions IoT Platform 24/7 from any location or device around the world. One of the main advantages of the Move Solutions IoT Platform is that it offers remote access to measurement data and allows remote configuration of all installed sensors. This saves time and labor. In addition, you can analyze the measurement data using processing algorithms included in the service. Perform complex calculations, correlations and analyzes automatically and effortlessly. With the touch of a button, you can export measurement data in CSV format. You can also easily configure alerts to multiple recipients who will receive threshold cross notifications via email.

  • Easily install the entire system on the structure without the use of wiring.
  • Configure all wireless sensors quickly and remotely.
  • View real-time measurement data wherever you are, on any device, 24/7.
  • Process the data collected through the implemented algorithms.
  • Constantly monitors the operating status and signal quality of the system remotely.
  • Customize your alarm notifications and receive overrun notifications by email.
  • Optionally, you can integrate data on your platform using an MQTT bridge, FTP or through API calls.
