摘要
近年来,随着汽车的发展,人们与汽车之间的联系日益密切,汽车车内空气质量也受到消费者越来越多的关注。在车内狭小的空间里,存在着各种有害气体,有害气体的污染主要由甲醛,苯等蒸汽造成,车内饰品的材料通常会释放出甲醛,苯等有害气体,因此对有害气体的检测就显得尤为重要。该文以一种基于有害气体传感器为基础,提出基于AT89C52单片机的汽车室内有害气体参数测试的整体设计方案,并用Proteus软件仿真整体电路系统,最终实现了实物的调试与验证。
Ab^tra~. In recent years, with the development of the automobile,the connection between the people and cars are becoming more and more close,vehicle's interior air quality also becomes more and more atten- tion.In the narrow space inside the car,there are all kinds of harmful gas.Harmful gas pollution is mainly composed of formaldehyde,benzene,interior decoration materials will usually release of maldehyde,ben- zene and other harmful gases,so for the harmful gas detection is particularly important.In this paper,based on a kind of harmful gas sensor,put the car indoor harmful gas parameter test of the overall design scheme based on AT89C52 microcontroller,and Proteus software simulation the circuit system as a whole. Finally achieved physical commissioning and validation. Key words: Sensor;AT89C52;Proteus simulation
