1、本科毕业论文--基于单片机多功能环境检测系统研究随着经济的发展,人们越来越关注污染程度日益严重的居住环境。他们开始利用高科技产品及时对居住环境进行检测,从而及时了解环境状况。伴随着单片机技术的飞速发展,通过单片机开发的检测仪器越来越小型化和多样化,然而对环境检测的多功能设备却很少被开发出来。本文主要介绍了基于单片原理开发的环境检测系统。该系统把单片机的控制技术和传感器技术相结合,开发成多功能环境检测系统。通过它对温湿度传感器、燃气浓度传感器、甲醒浓度传感器以及粉尘传感器的控制,实现对家庭环境的温湿度、燃气浓度、甲醒浓度、空气颗粒大小的采
2、集。采集的数值经过AID模数转换,再传输给单片机读取,然后传输给液晶显示屏显示,达到对室内环境的多功能检测和及时显示,使得室内环境状况一目了然。当检测值超出预设值时,单片机驱动蜂鸣器报警,使得用户及时发现环境的具体状况,从而为用户的居住生活带来舒适和安全。从而摆脱检测仪器的简单、独立的缺点而实现检测仪器的系统化、小型化、高效率和多功能。关键词:室内环境检测,单片机,传感器技术,PM2.5Abstract本科毕业论文--基于单片机多功能环境检测系统研究Withthedevelopmentofeconomy,peoplearepayingm
