摘要
近年来随着人们生活水准的提高,人们对于生活质量的要求也越来越高,同时也因为人们的各种仿制能力越来越强,通常会用低成本的原材料制造各种劣质的成品,比如:家具、各种家装饰品、汽车内饰等,而又难以通过直观的方式发现其是否含有有害气体,所以人们通常会对自己新装的房屋或者新购买的汽车等进行甲醛检测,以防范甲醛引发的各种疾病,所以该检测系统也就应运而生,而且受到广泛关注。该系统设计方案基于芯片,运用传感器,在系统传感亲模块输出的标准电流经A/D转换电路转换成为单片技能识别的信号,处理之后会将甲醛的含量显示在显示屏上,并发出声响以报警提醒,本设计操作简单,携带方便,价值极高。
In recent years, with the improvement of people's living standard, people's requirement to life quality is higher and higher, but also because of people's various imitation ability is stronger and stronger, they usually make all kinds of poor quality products with low cost raw materials, such as furniture, all kinds of home decoration, car interiors and so on, and usually it's difficult to identify whether there are harmful gases for people through naked eye, so they often check formaldehyde to their new house or new cars, in order to prevent various diseases caused by formaldehyde, so the detection system has emerged, and it has attracted more and more attention, the system's design scheme is based on the chip, using sensor to transform to a signal for the recognition of a single chip in the standard current output of the sensor module of the system converted by the A/D converter. Formaldehyde content will be displayed on the display screen after treatment, and sound to alarm, this design has the advantages of simple operation, convenient carrying, it has extremely high value.
