Community-Based Fire and Temperature Monitoring System with PIR Sensors for Enhanced Safety and Prevention

Abstract

Fire suppression systems typically rely solely on sirens for warning, without ensuring that individuals inside the building are accounted for during a fire emergency. This research proposes the design of an integrated fire suppression system that combines fire and temperature sensors with Passive Infrared (PIR) sensors to detect fires while simultaneously monitoring human presence within a room. The alarm system will activate upon detecting a fire, while the PIR sensors will assess the presence of individuals. If the PIR sensors detect no human presence, the ventilation system will be automatically shut off to reduce oxygen levels and prevent further escalation of the fire. The warning system will remain active until the fire is fully extinguished, at which point the ventilation will be restored. This study follows a comprehensive process of nine stages, beginning with the identification of the problem and concluding with final recommendations. Testing and various conditional scenarios were conducted to evaluate the system’s performance. The three sensors used—fire, temperature, and PIR—demonstrated good functionality overall. The data collected showed some error rates, which were influenced by external variables, but despite these minor discrepancies, all three sensors performed reliably. These findings suggest that the integrated system can be effectively implemented as a fire detection and safety system, offering a significant contribution to community safety. This research aligns with the broader goals of community service by providing an innovative solution that not only addresses fire hazards but also ensures human safety
