Wireless Sensor Networks (WSNs) have evolved from experimental gadgets to essential tools for smart infrastructure. Today, they underpin IoT deployments across cities, bridges, highways, and sectors like energy and manufacturing.
Key Transformations in SHM
From Wired to Wireless:
- Traditional SHM relied on wired sensors connected to DAQ boxes.
- Modern systems feature autonomous sensors with onboard microcontrollers, energy harvesters, and LPWAN connectivity (e.g., Sigfox, LoRaWAN).
Technological Drivers:
- Low-Power Microcontrollers enable edge processing to reduce data transmission loads.
- Energy Harvesting ensures years-long operation without battery replacements.
- Reliable Wireless Protocols like LoRaWAN ensure robust communication in noisy environments.
- Cloud + AI Integration enables predictive maintenance through real-time analytics.
Industry Landscape
Startups and SMEs dominate the WSN space with plug-and-play solutions, subscription-based dashboards, and partnerships with asset managers.
