Applications: Infrastructure tilting condition monitoring, such as retaining wall, supporting column, river embankment etc. From the 1st level of data conversion, the movement of one end of a beam/crossbar can be monitored, such as land sliding, railway track monitoring. With our latest developed mathematical model, we can achieve the Horizontal Convergence of a metro tunnel of 6 segments.

      Tilting Orientation

      1)  When holding the Spec paper horizontally, then when X-axis arrow rotates

           around 0-dot into the paper plane, the readings of "x" decreases; It also applies

           to both Y/Z-axis;
      2)  The node fixings must be rigid for the sensor to measure accurate data.

           Movement in the fixings will affect the readings;
      3)  The Omni Tilt Sensor Nodes must be oriented with any two axis marked on the

           label parallel to the horizontal plane, so that the data can be easily interpreted.
