摘　　要：实时CO浓度检测报警是基于单片机AT89S52系统。使用对一氧化碳敏感的TGS2600-B00传感器对空气中的CO进行采样检测,通过传感器电阻值的变化反映出浓度的变化,再经模数转换器ADC0809转换后由单片机进行数据处理,并在LED上实时显示出当前CO的浓度,在超过30×10-6时报警。该系统具有灵敏度高、结构简单、体积小、携带与安装方便等特点,具有较高的应用价值。Real-time CO concentration detection alarm system is based on single chip microcomputer AT89S52. A sensitive carbon monoxide TGS2600-B00 sensor is used for detecting CO samples in the air. The sensor resistance changes reflect the change of the concentration. It treats the data are converted by AD converter ADC0809 before they are processed by single-chip computer. The current CO concentration is showed on the LED in real time and an alarm is activated if it exceeds 30 × 10^-6. This system has the advantages of high sensitivity, simple structure, small size and easy installation. It can find applications in avoiding traffic accidents and monitoring physical and mental health.
