The document discusses the design and implementation of a cost-effective and reliable GSM-based fire alarm system aimed at preventing fire accidents, which can cause significant loss to life and property. The system utilizes an Arduino Uno microcontroller integrated with a flame sensor, GSM module, LCD display, and a buzzer to provide alerts through SMS and audio signals when fire is detected. This automated approach is intended to ensure timely notification to occupants and enhance safety in both residential and industrial settings.
