Structural crack is one of the most preliminary sign for deterioration of structural integrity. We extended our service to provide a REAL-TIME solution for monitoring of wide and very wide cracks (> 2cm) on buildings and infrastructures. The crack sensor is placed perpendicular to the crack line, and perpetually monitors the crack width. Once the crack width increases and reached the safety limits, the sensor will communicate to the Cloud server and hence trigger escalation the respective stakeholders.
