Floods, earthquakes, fires—they can turn everything upside down in a moment. Fast detection and quick action save lives and property. In this paper, I introduce an IoT Disaster Detection and Rescue System that spots these disasters as they happen. It uses sensors to pick up floods and earthquakes, plus a camera powered by YOLO to catch fires. The ESP32 microcontroller pulls all this data together and shoots out alerts right away using a GSM module. The whole setup is straightforward, affordable, and actually makes emergency response faster and more reliable.
