Heritage Monument Structural Health Monitoring

• Aging stone masonry with visible crack formations

• Sensitivity to drilling or invasive installations

• Environmental impacts (temperature & humidity variation)

• Urban vibration due to nearby traffic

• Limited access for wired infrastructure

GeoLook designed and deployed a non-invasive wireless SHM system consisting of:

• Crack meters installed across major fracture zones

• High-precision tilt sensors on structural towers

• Triaxial accelerometers for vibration monitoring

• Environmental sensors (temperature & humidity)

• Centralized multi-channel data logger

• Cloud-based analytics dashboard

All sensors were integrated into a secure IoT platform with remote access and automated alert triggers.

• Wireless Tilt Sensors

• Vibrating Wire Crack Meters

• MEMS Accelerometers

• Multi-Channel Data Acquisition System

• 4G/LoRa-Based Gateway

• Web-Based Monitoring Dashboard

• Early detection of micro-tilt movement

• Crack progression trend analysis

• Reduction in manual inspection costs

• Real-time alert system for abnormal vibration

• Data-backed conservation decision support

The monitoring system now provides continuous structural performance insights and ensures proactive preservation of the monument

• Improved heritage asset lifespan

• Reduced structural risk

• Remote monitoring capability

• Data-driven conservation planning

• Long-term infrastructure sustainability
