Abstract

In a building fire event, occupants are distracted by thick smoke and carbon dioxide fumes that result in an unguaranteed evacuation. Using the conventional exit signs to the exit doors is insufficient to guide the occupants from safety while it becomes more critical in the multi-story buildings. Even finding an exit door is a risk as exiting a door without a clue of what lies on the other side of the door is a great threat. Therefore, there is a need to develop a system to guide the building occupants in evacuation. The system can identify and analyse the presence of real-time fire in the specific location of a building and send a warning notification when the threshold levels are exceeded. The “traffic light” concept system is indicated with piezo buzzers and flashing red and green LEDs located at the exit points. This project involves Internet of Things (IoT) technology using NodeMCU ESP32, ThingSpeak platform, and Pushover application. The experimental result shows that whenever the temperature, gas and flame levels are beyond the threshold, the authorised individuals receive a notification on the respective Wi-Fi connected mobile devices. Through this project, the evacuation will become efficiently faster and safer.
