Development of an IoT based fire alarm monitoring system

Existing buildings without a fire alarm monitoring system need an alternative installation cost-effective, flexible, and scalable and will not affect the building's aesthetics. In place of the conventional fire alarm monitoring system, an Internet of Things (IoT)fire sensor nodes were designed to monitor each room's temperature and analog CO level and deploy through point to point technique. An IoT fire alarm monitoring system using a wireless sensor network was developed through which real-time data of temperature and analog CO level were obtained from the fire sensor nodes. The IoT fire sensor nodes were deployed from rooms LB384 to LB387. Each room has a node, and each node has its designated Internet Protocol (IP) address. The data can be easily obtained and accessed through the cloud web server, and each IoT fire sensor node will send a notification to the user of the room through the IoT ThingSpeak monitoring widget. The IoT fire alarm monitoring system reduced the installation time and did not require significant building renovations based on the assessment. With the advancement of IoT, fire detection could then be realized such that people within buildings can have a good understanding of the safety of their living environment.
