III. SYSTEM OVERVIEW

Fig. 3. Flow of Disaster Management System

As we recognized IoT structures can help to shield humans and the environment from natural failures. By using sensors to monitor situations like climate and water stages, we can offer early warnings and help citizens prepare and respond successfully provided the picture shows the workflow of an IoT gadget that is designed for catastrophe management. This machine makes use of a combination of sensors, a microcontroller, cloud connectivity, and a GSM module to gather, system, and examine information related to environmental situations.

This manner starts with the relationship of diverse sensors to a microcontroller. Those sensors are intentionally deployed to collect records on parameters including temperature, humidity, strain, fuel ranges, water degrees, and seismic hobby. The microcontroller, acting as the gadget's mind, gets and techniques the sensor data, figuring out patterns, abnormalities, or threshold crossings that could imply a potential disaster. As soon as the statistics have been processed, its miles transmitted to a cloud-primarily based platform for storage, analysis, and visualization. This allows for centralized information control and allows faraway monitoring of the state of affairs. If the facts show a crucial occasion, including a fast growth in temperature or water tiers, the gadget can trigger indicators to the citizens, along with sending SMS messages, making telephone calls, or activating sirens. Those signals may be directed to applicable government, emergency services, or the affected populace regions. To facilitate communique, the system incorporates a GSM module, which permits connectivity to cell networks. This permits the transmission and reception of statistics, such as SMS messages and contact calls.

The amassed statistics also can be visualized on a dashboard or map, providing a real-time evaluation of the scenario and assisting in choice-making.
