A Multilevel Home Fire Detection and Alert System Using Internet of Things (IoT)

A home fire alert system can safeguard lives while limiting damage to the greatest extent possible. However, it will be easier to implement the necessary safety measures if the fire alert system can assess the threat based on several fire hazard levels. In this paper, we proposed a multilevel home fire detection and alert system using the Internet of Things (IoT). This system's goals are to detect the multilevel fire characteristics parameter, keep track of them, and send multilevel fire alerts to the user(s) based on fire hazard levels so that they can take the necessary actions. We have utilized two different sensors for fire detection. These sensors sense fire characteristic parameters such as temperature, humidity, and gas levels and send them to the connected NodeMCU. A system user can view the information through the LCD, a Smartphone app, and a cloud server. When the temperature and humidity or gas levels exceed the predetermined threshold values, a buzzer activates, an LED light switches from green to red, and an alert shows on the Smartphone app and cloud server. If all of the fire characteristics parameter levels go beyond the threshold value, with previously taken steps, an extreme fire alert will be transmitted to the fire brigade's email address, and a red-filled circle alert will appear on the cloud server. We have designed a prototype to show the effectiveness of the proposed system. The prototype has undergone planned testing, and the results demonstrate that the functionalities of the proposed system are operating as expected within a reasonable response time.
