IOT-ENABLED MULTISENSOR FUSION FRAMEWORK FOR REAL TIME FIRE HAZARD AND GAS LEAKAGE DETECTION

The IoT-Based Fire and Gas Leak Detection System use an ESP32 microcontroller to monitor conditions. This IoT-Based Fire and Gas Leak Detection System bring together a gas sensor, a flame sensor and a DHT11 temperature and humidity sensor to watch the environment and spot situations when the readings cross set limits. The IoT-Based Fire and Gas Leak Detection System show alarms with LEDs and a buzzer right at the spot. It also sends the sensor data over Wi‑Fi to a laptop that runs a web interface. The IoT-Based Fire and Gas Leak Detection System give alerts and lets users check the data from a remote computer. I think the IoT-Based Fire and Gas Leak Detection System is very useful for keeping everyone safe. The web dashboard offers a way to look at sensor readings, environmental measurements and hazard alerts without needing an OLED screen. This method brings together embedded processing, wireless communication and web-based display in a low-cost model. I find it useful to see everything on my laptop. Possible upgrades could be storage for data alerts, on phones, backup power, better sensor calibration and predicting dangers using data. More testing is needed to check how accurate the system is, how fast it reacts and how reliable the communication is. The system can help with knowing about dangers and reacting quickly. It should be used along with fire and gas safety tools, not instead of them. believe the IoT-Based Fire and Gas Leak Detection System should be used with proper safety tools.
