Complete guide to BuildGuard structural health monitoring system

System Overview

BuildGuard is an advanced IoT-based structural health monitoring system designed to protect buildings and save lives. It uses a network of sensor nodes (Node D) and receiver gateways (Node C) to continuously monitor structural integrity in real-time.

The system detects earthquakes, ground movements, structural weaknesses, corrosion, and water leaks by analyzing data from accelerometers, magnetometers, temperature, humidity, and pressure sensors.
