Abstract
With the application and development of Internet of things technology, the demand for home intelligent devices is higher and higher. Home fire safety is particularly important. In view of the current home fire safety problems, this paper proposes a home fire alarm system based on the combination of microcontroller and sensor. The system takes microcontroller and sensor as the main components, and uses the combination of combustible gas detection module, temperature detection module and flame detection module to form a fire alarm system. The functions of gas leakage early warning exhaust, fire sound and light alarm exhaust and high temperature detection alarm are realized. Combustible gas detection, temperature detection and flame detection all collect data through sensors, and then compare with the preset alarm value to judge whether the fire occurs. The design has the advantages of accurate detection, high degree of intelligence, convenient installation, strong scalability and so on. It gives a new solution to the fire safety of the home.
