Abstract :

- Fire alarm systems play a critical role in safeguarding lives and property by providing early warnings in the event of a fire outbreak. However, traditional fire alarm systems often involve complex wiring and installation procedures, which can be daunting for users and deter them from implementing such safety measures in their homes. To address this challenge, we propose an innovative solution: an Internet of Things (IoT) based wireless fire alarm system designed for easy installation and operation. The core of our proposed system is an ad-hoc network distributed throughout the house, comprising microcontrollers such as the ESP8266 NodeMCU. These microcontrollers are equipped with infrared flame sensors, continuously monitoring the surrounding environment for signs of fire. Importantly, the microcontrollers establish their own Wi-Fi network, enabling seamless communication and coordination within the system. When a fire is detected by any sensor within the network, a signal is promptly transmitted to the corresponding microcontroller. This triggers a series of predefined actions, including sending an SMS alert to the user, initiating a phone call to notify them of the emergency, and activating a local alarm within the house to alert occupants. Additionally, users can proactively query the system for real-time updates on their home's status by sending an SMS command. To validate the efficacy of our proposed system, we developed a prototype and conducted rigorous testing. The prototype successfully demonstrated all desired functionalities, achieving rapid response times with an average delay of less than 30 seconds. Through this innovative IoT solution, we aim to empower users with a reliable and user-friendly fire alarm system that enhances home safety and peace of mind.
