大气参数检测系统总体方案设计

摘要我国是正处于高速发展中的大国，在工业化规模不断扩大的同时，环境污染问题也日益严重。近几年来，随着人们环保意识的提高，人们越来越关注大气空气污染问题对人身体健康的影响。在我国，大气空气污染主要是由于工业废气的排放、空调的大量普及和可吸入性颗粒引起的，其中可吸入性颗粒主要指PM2.5，而且大气中的温湿度等信息对于农业和社会发展至关重要。所以本文设计了一款基于单片机的大气数据测量系统，以PM2.5传感器、温湿度传感器以及烟雾传感器为核心，以LCD显示器为显示模块，并辅助以按键电路、数模转换电路等，实现对于大气的可吸入颗粒物、温湿度等指标的检测。本系统采用模块化设计，并对系统的整体设计功能做出了检测。关键词：大气数据测量；AT89C58单片机；温湿度AbstractChina

of

which

the

inhalable

mainly

refer

to

is

crucial

for
