Abstract
This project presents a low-cost, efficient fire alarm system utilizing an Arduino microcontroller. The system is designed to detect fire hazards by monitoring environmental temperature and smoke levels through sensors such as the DHT11 (temperature) and MQ-2 (smoke) sensors. When the sensor readings cross predefined thresholds, the Arduino triggers an alarm using a buzzer or activates further safety measures like alert notifications or turning on exhaust fans. This compact and reliable system is ideal for residential, commercial, and industrial safety applications. It demonstrates how embedded systems and sensors can be integrated to provide a real-time, automated fire detection solution.
