基于单片机的甲醛检测器设计摘要我国社会在不断的进步，人们的生活随着科技与经济的不断发展，质量得到了大幅提升，对“健康生活”的需求内容也发生了变更，我们已经从“活着”转变为“活的好，活的舒服，活的健康”。受传统观念及文化影响，中国人对购房可谓有一番执念，而刚装修好的新房往往会散发出甲醛，因此，检测新房装修材料带来的甲醛浓度检测已经成为了当下一个十分常见的现象与需求，成为了生活舒适度的衡量标准之一。本文将要提出的就是一个各组部分齐全的甲醛检测系统，检测部分主要采用的是甲醛模组传感器，为方便使用，有设置系统键盘模块，还加入了警报电路与液晶显示两个模块，便于甲醛超标时的即时信息反馈，本系统核心采用的是C51系列的STC89C52RC，各组部共同运作，发挥检测系统的全部功能。本课题的目标是设计一款市民可以在家中独立完成的便捷、灵敏、直观、准确、经济的甲醛检测仪器，以提高人们的生活质量，让人们拥有更健康的生活。关键词：单片机，（；）甲醛检测器，按键模块，报警电路，液晶显示PAGE\*MERGEFORMATIVThedesignofformaldehydedetectionsystembasedonAT89C52AbstractWiththedevelopmentofsociety,people'slivingstandardscontinuetoimprove,thereis"foodandclothing"to"well-off",fordecorationmaterialstoemitformaldehydeconcentrationdetection,toprovideareferencestandardforthesafetyandcomfortofpeople'slives.Inthispaper,theC51seriesofSTC89C52RCasthecontrolcore,formaldehydemodulesensormoduledetectioninformation,setupthesystemkeyboardmodule,alarmcircuit,liquidcrystaldisplay,compositionofformaldehydedetectorsystemassemblytoachieveallthefunctions.Keywords:Singlechipmicrocomputer，Formaldehydedetectionsystem，Thekeymodule，Alarmcircuit，LiquidcrystaldisplayPAGE\*MERGEFORMATIV目录摘要..............................................................................................................................................IAbstract...........................................................................................................................................II第一章前言或引言....................................................................................................................11.1设计背景................................................................................................................................11.2甲醛检测研究现状................................................................................................................31.3设计目的................................................................................................................................4第二章系统主要器件的介绍.......................................................................................................52.1主控制器................................................................................................................................52.2LCD1602.............................................................................................................................122.3甲醛模组ZE08-CH2O........................................................................................................15第三章系统硬件设计.................................................................................................................173.1最小系统部分......................................................................................................................173.2复位电路..............................................................................................................................173.3时...
