The system is designed for 99.9% uptime with disaster recovery provisions.

Both vibrating wire (VW) and MEMS sensors are used in structural monitoring, each with distinct advantages:

Vibrating Wire Sensors:
• Working Principle: Measure the resonant frequency of a tensioned steel wire, which changes with strain
• Long-term Stability: Excellent stability over decades with minimal drift
• Durability: Highly resistant to moisture, corrosion, and electrical interference
• Power: Can operate with lower power consumption in remote applications
• Best For: Long-term monitoring (10-30+ years), dam monitoring, critical infrastructure
• Limitations: Slower response time, requires specialized readout equipment

MEMS Sensors (Micro-Electro-Mechanical Systems):
• Working Principle: Use microscale mechanical elements that change electrical properties under stress
• Response Time: Fast dynamic response suitable for vibration monitoring
• Cost: Generally lower cost per unit
• Size: Compact form factor, easier installation
• Best For: Dynamic monitoring, vibration analysis, temporary installations, high-frequency measurements
• Limitations: May have more long-term drift, sensitive to temperature variations

Geolook Recommendation:
For permanent infrastructure monitoring requiring decades of reliability (dams, major bridges), vibrating wire sensors are preferred. For dynamic monitoring, construction phase monitoring, or cost-sensitive projects, MEMS sensors offer excellent value. Many projects use both types for comprehensive coverage.
