Wireless sensor networks (WSN) in recent times have become a dominant technology in environmental monitoring and in early detection of conditions like fire outbreaks in order to save lives and properties. In this article, the design and development of a WSN fire detection system is presented. For accurate and reliable detection of fire, three sensors (i.e., MQ-2, DS18B20, and KY-026) are employed in addition to other WSN key components for the respective detection of gas, temperature, and infrared, which are major fire parameters. The system further has a battery monitoring scheme for the observation of the energy resource of the nodes and to ensure their viability. A developed graphic user interface is deployed for the remote monitoring of the entire system and its data. Results obtained from the different test conditions using combustible solid, inflammable liquid, and gas show that the system performed optimally. The developed system is recommended for residential and small office applications.
