基于单片机的PM2.5检测与净化系统设计

Design of PM Detection and Purification System Based on Microcomputer

随着社会的发展,环境污染问题越来越严重,PM2.5是空气质量的重要指标,所以PM2.5的检测就很重要,通过设计的PM2.5检测仪围绕单片机为控制核心,完成数据的采集、显示、参数设置、报警及净化等系统各模块的程序设计,结合各模块的硬件电路实现每个模块的功能,从而实现整个系统的功能。该检测仪主要用于检测环境中的PM2.5浓度,适用于劳动部门生产现场粉尘浓度的测定、环境环保监测部门大气飘尘检测和污染源调查等。

With the development of society,the problem of environmental pollution is getting more and more serious.PM2.5 is an important indicator of air quality.Therefore,the detection of PM2.5 is very important.The PM2.5 detector is designed around the single-chip microcomputer as the control core to complete the data.The program design of each module of the system such as acquisition,display,parameter setting,alarm and purification,combined with the hardware circuit of each module to realize the function of each module,so as to realize the function of the entire system.The detector is mainly used to detect the PM2.5 concentration in the environment,and is suitable for the measurement of dust concentration on the production site of labor departments,the detection of atmospheric dust in the environmental protection monitoring department,and the investigation of pollution sources..
