Description
The Dynamic Displacement Sensor is a wireless device that remotely monitors the dynamic displacement and the frequencies of infrastructures.
The dynamic displacement measures the quick displacement of a structure due to dynamic forces, during events such as strong winds, machinery operation, heavy traffic or earthquakes, and it is typically represented as a distance in millimetres (mm). The frequencies measure the rate at which a structure vibrates or oscillates when subjected to dynamic forces, and they are expressed in Hertz (Hz).
The data collected is visible via Move Solutions IoT Platform, where each sensor can also be configured, allowing users to remotely set and change specific thresholds according to their needs. When the amplitude surpasses this threshold, the sensor records and transmits vital information, covering the 10 seconds leading up to the event and 20 seconds thereafter. This comprehensive dataset is essential for in-depth analysis.
