The role of IoT sensor in smart building context for indoor fire hazard scenario: A systematic review of interdisciplinary articles

In recent years, there has been growing interest in using Internet of Things (IoT) sensors to address indoor fire hazards in smart buildings. This study conducted a systematic review of 54 articles from interdisciplinary databases using selected keywords over the past decade, with the aim of investigating the potential role of IoT sensors in indoor fire hazard contingency. Through thematic analysis, five main themes and 24 sub-themes were identified, including vision-based sensing, smart automation, evacuation and indoor navigation, early fire detection, intervention and prevention, and BIM-related. The results of this review indicate that there are numerous aspects of indoor fire hazards that could benefit from the use of IoT sensors, and that the recurrence of technical terminologies in the analysed articles underscores the importance of these technologies in establishing an IoT sensor network in smart building environments, particularly in addressing indoor fire incidents. The outcome and findings spurred a concept for potential future research ideas. As a result of the findings, a conceptual framework for IoT sensors in the context of smart buildings is proposed.
