摘要
设计了一种基于PIC16F877A单片机、能有效检测出甲醛及苯的室内有害气体检测系统,详细描述了该系统的硬件和软件设计方案。软件设计中采用温度补偿技术对测试结果进行了温漂校正,提高了室内有害气体测试的准确度。该检测仪能及时提醒人们居住环境中的有害气体含量,对确保人们居住环境安全有重要意义。
A kind of indoor harmful gas detection system based on PIC16F877 A is designed, which can effectively detect the formaldehyde and benzene. The designing scheme for hardware and software of the system is described in detail. The temperature compensation technology is adopted in the software design, and the temperature drift of the testing results has been corrected, which improves the testing accuracy of indoor harmful gas. The detector could timely remind harmful gas content in people's living environment, and has important significance for ensuring the people's residential environment security.
