Deck
The Deck sensor is a wireless device capable of measuring dynamic displacement amplitude with an accuracy of 0.01 mm and the vibration frequency of any structure on which it is installed, using an FFT algorithm. A threshold can be configured remotely for each sensor through the Move Cloud platform. Each sensor continuously samples the oscillation amplitude and, when this threshold is exceeded, records and transmits the 10 seconds before and the 20 seconds after the event. It is completely wireless, and the battery can last for years. It also features an integrated temperature sensor.
The Deck sensor transmits accurate readings from the site through a gateway using the LoRaWAN wireless communication protocol. Data can be viewed and managed online through the Move Cloud platform. Several data processing and correlation algorithms developed by Move are available. It is ideal for the dynamic monitoring of large structures such as bridges and overpasses.
Each sensor continuously samples the oscillation amplitude and, when the configured threshold is exceeded, records and transmits the 10 seconds before and the 20 seconds after the event. It is completely wireless, and the battery can last up to eight years.

Main applications of the dynamic displacement sensor
Easy installation of the Move wireless monitoring system
Installing a complete wireless sensor system on site is quick and easy: simply secure each device to the structure to be monitored using at least two screws and power the LoRaWAN gateway. The entire system can be configured remotely before, during or after installation using a laptop or tablet. Once the system has been installed and configured, the Move wireless monitoring system will begin taking measurements, allowing remote monitoring to start immediately.
How the Move wireless monitoring system works
The wireless sensor system automatically transmits measurement data via LoRaWAN to the on-site gateway, which then sends the received data via 4G or LTE to the online servers. The Move Cloud Platform is a cloud-based web tool that allows users to access, view and export measurement data and configure the settings of the entire sensor system. The Move Cloud Platform can be accessed 24 hours a day, 7 days a week, from anywhere in the world and from any device. One of its main advantages is that it provides remote access to measurement data and enables the remote configuration of all installed sensors, saving both time and labour. Measurement data can also be analysed using the processing algorithms included in the service. Complex calculations, correlations and analyses can be performed automatically and effortlessly. Measurement data can be exported in CSV format at the touch of a button. Alerts can also be configured for multiple recipients, who will receive threshold-exceedance notifications by email.
- Easily install the entire system on the structure without any wiring.
- View measurement data in real time, wherever you are and from any device, 24 hours a day.
- Configure all wireless sensors quickly and remotely.
- Process the collected data using the implemented algorithms.
- Continuously monitor the operating status and signal quality of the system remotely.
- Customise alarm notifications and receive threshold-exceedance alerts by email.
- Optionally integrate the data into your own platform through an MQTT bridge, FTP or API calls.
