Introduction
With the advancement of technology and the improvement of living standards, natural gas and gas have gradually entered our homes, bringing us convenience, but also potential hazards. Gas leakages can lead to explosions, posing threats to our lives and property. Therefore, the detection and alarm of gas leaks has become a necessary task. This paper proposes a design of a gas alarm system based on the 80C51 single-chip microcomputer, which uses sensors to detect the concentration of gas in the environment and converts the concentration value into a digital signal recognizable by the single-chip microcomputer through A/D conversion. When the gas concentration exceeds the preset value, the single-chip microcomputer triggers the alarm through the sound and light alarm system. The design of this system fully utilizes the advantages of the single-chip microcomputer, such as simple circuit, low cost, and good reliability, to achieve real-time control of the gas alarm system. Meanwhile, the use of the single-chip microcomputer's simple programming and fast operation speed enhances the system's performance, accuracy, and sensitivity. Through the design and implementation of this gas alarm system, the safety hazards of gas poisoning and explosions have been effectively addressed, providing a certain guarantee for the safety of homes and society.
