  • In this paper, we propose a Wi-Fi Mesh-based fire detection system for fire detection and rapid response. Previous fire detectors had the problem that it is difficult to distinguish between fire and non-fire based on a single sensor, and since multiple detectors operate independently, there is a lack of interconnectivity. In this paper, we present a fire detection system based on a K-NN classification model using a multi-sensor based fire detector. Also, by constructing a mesh network for fire detection, detectors within a spatial range can be interlinked to detect fire. Looking at the performance evaluation results of the implemented system, it was confirmed that the TPR(True Positive Rate) of fire classification was 96.1%, the FPR(False Positive Rate) was 0%, and the F1-Score, which corresponds to the harmonized mean value of accuracy and reproduction rate of fire and non-fire classification, was 98.01%, and the prediction accuracy ACC(Accuracy) showed excellent performance of 98.05%. In the future, we intend to develop it into an intelligent fire detector system through mesh network monitoring and multi-sensor self-diagnosis functions.
