ABSTRACT: This paper presents the design and implementation of a cost-effective Fire and Smoke Detection System using Arduino aimed at enhancing safety in residential, commercial, and small-scale industrial environments. Fire hazards pose a significant risk to life and property, necessitating the development of reliable early detection systems. The proposed system employs an MQ-2 smoke sensor and a temperature sensor (LM35/DHT11) to continuously monitor environmental conditions. These sensors detect variations in smoke concentration and temperature, converting them into electrical signals that are processed by an Arduino-based microcontroller. The microcontroller compares real-time sensor data with predefined threshold values and activates alert mechanisms such as a buzzer and LED indicators when abnormal conditions are detected. The system is designed to ensure rapid response, high sensitivity, and operational reliability while maintaining low cost and ease of implementation. Experimental testing, including smoke and heat analysis, demonstrates effective performance in detecting fire-related hazards with minimal delay. Furthermore, the modular architecture of the system allows future enhancements such as IoT integration for remote monitoring and automated emergency response. This work highlights the importance of embedded systems in safety applications and provides a practical solution for early fire detection.
