ABSTRACT: This project addresses the critical issue of fire safety, particularly in environments where liquefied petroleum gas (LPG) is used. LPG presents a significant fire hazard due to its combustible nature, posing risks to both life and property. The Automated LPG Fire Suppression System (ALPG-FSS) aims to mitigate these risks by providing an autonomous and efficient method of detecting and suppressing LPG fires. The system employs infrared flame detection sensors to identify fire occurrences and a microcontroller to analyze sensor data and trigger appropriate responses. Upon detecting a fire, the system activates a blower fan to disperse a suppression agent, such as sodium bicarbonate, aimed at extinguishing the flames. Additionally, an alarm system alerts occupants to the presence of a fire, facilitating timely evacuation and further enhancing safety measures. This system further allows for remote monitoring and control on a mobile device via a Blynk mobile application that accesses system data and status from the ESP 32 microcontroller. The technology behind the ALPG-FSS combines hardware components, such as sensors, microcontrollers, and actuators, with software algorithms to create an integrated fire suppression solution. Infrared flame detection sensors enable the system to detect LPG fires based on the presence of infrared radiation emitted by flames. The microcontroller serves as the brain of the system, processing sensor data and executing predefined algorithms to initiate suppression actions when necessary. Actuators, such as the blower fan, provide the mechanical means to disperse suppression agents effectively. Overall, the ALPG-FSS represents a sophisticated integration of hardware and software technologies, tailored to address the specific challenges associated with LPG fire hazards and enhance fire safety in various settings.
