IoT systems can be designed for resilience against natural disasters like floods or earthquakes by integrating robust sensor networks, predictive analytics, and real-time monitoring. Smart sensors can detect early signs of structural stress, water levels, or seismic activity, providing timely alerts to minimize damage. Redundant communication channels such as satellite or mesh networks ensure uninterrupted data flow even if traditional networks fail. Additionally, cloud-based platforms can analyze incoming data to guide quick decision-making and emergency response. Building resilient IoT systems enhances disaster preparedness and community safety. Strengthening these skills is possible through an IoT professional certification.
