Abstract. This project involves the integration of multiple sensors and actuators to create a
comprehensive safety monitoring system using an Arduino microcontroller. The primary
components include a flame sensor, an MQ2 gas sensor, an OLED display, LEDs, a buzzer, and a
fan. The flame sensor detects the presence of fire or excessive heat, triggering visual and audio
alerts via LEDs and a buzzer. The MQ2 sensor monitors for hazardous gas concentrations,
similarly activating alerts to warn of potential danger. Additionally, a fan is incorporated to help
dissipate harmful gases and reduce risk. The OLED display provides real-time data visualization,
enhancing the system’s usability. This project demonstrates the practical application of Arduino in
developing a low-cost, effective safety solution for fire and gas leak detection. The results highlight
the system’s capability to promptly respond to d
