Abstract

This paper presents an IoT-based fire detection system that integrates multiple sensors (MQ2, DHT11, and PIR) with an MQTT communication protocol to enhance detection accuracy and reduce false alarms. By combining multiple sensors, manual override mechanisms, and a real-time dash-board interface, the system allows emergency response while providing flexibility for user interven-tion in case of failures. The system is protected with TLS encryption in order to protect the data in-tegrity in such a crucial system. The tests taken regarding this system confirm the reliability of the alerts and the robustness of the system performance in simulated scenarios.
