SMART FIRE & GAS SAFETY SYSTEM: AN IOT-INTEGRATED SYSTEM WITH BLUETOOTH CONTROL USING LABVIEW

Abstract: Fire and gas leak incidents pose significant threats to safety in industrial and residential environments. This work presents a real-time fire, gas, and temperature monitoring system designed for early hazard detection and prevention. The system integrates an MQ-5 gas sensor, a single-channel flame sensor, and an LM35 temperature sensor to continuously monitor environmental conditions. In the event of a gas leak or fire detection, an alarm system comprising a buzzer, LED indicators, and an automated sprinkler system is activated to mitigate risks. To enhance system control and accessibility, Bluetooth communication allows users to manually control the sprinkler, buzzer, and LED using a mobile application via predefined commands. Additionally, the system is equipped with IoT-based remote monitoring through Firebase, enabling real-time data storage and analysis. The data transmitted to real time database which includes gas and fire status, temperature readings, and system responses, ensuring remote visibility and decision-making. The system is implemented using MyRIO as the central processing unit, interfacing with LabVIEW for real-time monitoring. The proposed system enhances safety, automation, and monitoring efficiency while providing seamless remote accessibility. Experimental results demonstrate the system’s effectiveness in detecting hazards with high accuracy and rapid response time.
