Infrastructure Monitoring with Dynamic and Static Wireless IoT Sensors

The safety and reliability of dams, buildings, and tunnels depend on their structural integrity, which can be affected by various factors such as seismic activity, ground deformation, and aging. Regular monitoring of critical parameters such as deformation, stress, and crack propagation is essential for detecting early warning signs of structural damage that can compromise the safety of people and property.

Advanced technologies such as inclinometers, accelerometers, crackmeters and strain gauges can be utilized for real-time monitoring of these infrastructures, such as:

Buildings • Dams • Vertical Structures • Tunnels
