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
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.
As shown below, readings (of the blue axe) get smaller from Status 1 to Status 2; increase from Status 1 to Status 0.
Infrastructure tilting condition monitoring of accuracy 0.01°, 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 (with accuracy of 0.17mm/m), such as land sliding, railway track monitoring.
With our latest developed mathematical model, we can achieve a 0.3mm accuracy for the Horizontal Convergence of a
metro tunnel of 6 segments.

Earth Magnetic Field Intensity Distribution Compass On-site Calibration Procedures
1. Accuracy: The Yaw value is merely depending on the correct measurements of Earth Magnetic Intensity;
2. Calibration: Any magnetic distortion that affects a node at a fixed relative direction of a fixed value (e.g., X uT) (providing
X uT is < < the up limit of the sensor, i.e., 2500uT in this case), then the distortion can be calibrated;
3. Stability: the measurements of Yaw can only be stable if the magnetic fields has no change (apart of the Earth Magnet
due to node rotation) after the calibration.
Notice: Magnetisable parts that is NOT able to fit into Principle 2, then it will severely affect the level of Calibration and
hence the Yaw Accuracy. In this case, these parts must be kept at a minimum 30cm plus away from a Omni Tilt & Compass
Sensor Node; Examples:
A. Typical magnetisable parts: e.g., reinforced concrete, fence, etc.;
B. Typical parts that can be calibrated: the accessories on a node, e.g., the stainless steel screws, rotation brackets,
However please note! Accessories MUST be fixed on a node before any calibration begins (hence Principle 2).
Step 1: Measurement Reference:
At the exact installation position, measure the surface orientation (i.e., Yaw) by a compass or the App on a smart phone,
write down the reading (i.e., Yaw_ref).
Step 2: 90s Slow Preparation Buzzer (0.5s on + 1.5s off)
Fix the brackets and accessories (such as, screws and antennas) onto a node, power the node on and see all three mesh
LEDs flashing 3 times. Then close the lid by tightening the 4 screws, then overturn the nodes 3 times so that the lid surface
and the bottom surface can face upward 3 times respectively.
Step 3: 120s Quick Calibration Buzzer (0.5s on + 0.5s off):
Seq. Lid Orientation Antenna Connector Orientation Slowly rotate a node around one axis shown on the label for 3 full circles (3s/circle) 1 Face to the customer Points up Round X-axis. 2 Points left Round Y-axis shown on the label. 3 Points right Round Y-axis shown on the label.
Note: iterate according to Seq. 1, 2 & 3 shown in the table above until “Confirmation Buzzer” is on.
Step 4: 10s Confirmation Buzzer:
Sound Confirmation Flag in Data Calibration Result Single Beep (10 times) Flag=0 Success Double Beep (10 times)”
Flag≠0， Redo calibration.
Step 5: Mesh Data Comparison:
Ensure the installed node is within ±8° offset from Yaw_ref recorded in Step 1;
Step 6: Error Flag Diagnostics:
For all the Flag≠0, please refer to “Flag ID Diagnostics Table”.
Flag ID Diagnostics Table
Basis: Based on the latest Specification for on-site calibration and the observation of at least 3 continuous sets of data, then
carry out the analysis as stated below:
Flag ID Description Suggested Solution 0 Working --- *9 Calibration Failure due to incorrect calibration. Strictly follow the procedures in “Specification” and recalibrate. *16 Node is restarted, no calibration is performed, the latest calibration has been successful and the latest calibration setting is reused.
Compare the Yaw°, X°, Y°, Z° data with their historic sets:
- if the data stays relatively unchanged, then no need for any further actions;
- or strictly follow the procedures in “Specification” and recalibrate.
*24/25/26/27 Module of Magnet Vector > 2500uT. Keep node away from the magnet disturbance, then strictly follow the procedures in “Specification” and recalibrate.。
Module of Magnet Vector ∉ [20uT, 61uT), or Module of Acceleration Vector ∉ [0.9g, 1.1g], or Self-test failed. If the data cannot be recovered by itself or remain unacceptable, then revisit the site, and keep the node away from the magnet/vibration disturbance, then strictly follow the procedures in “Specification” and recalibrate. Rest Cases such as Water ingress, damage on the node etc.; Data is lost or shown unexpected behaviors. Hardware fault, please contact Technical Support.
*: After 2-3 rounds of recalibrations, if the Error Flag is identical among themselves, then it leads to a potential hardware
failure, which is usually caused by a direct contact to a strong magnet.
Installing in none-magnetisable structure for long term Euler angles (Yaw, Pitch and Roll) monitoring, such as Tree monitoring.
