基于单片机的湿度控制系统设计【摘要】生活上，合适的空气湿度有益于人们的身体健康；工业上，芯片的封装，设备的维护以及工厂的装配等，都需要在合适的湿度下进行。该课题对空气的湿度进行讨论,采纳单片机和湿度模块组成的湿度控制系统，对环境的湿度进行数据采集、处理。系统通过测量当前环境的绝对湿度，及时、精确地了解空气湿度的变化，并将当时绝对湿度值与预设的上下限值进行比较，假如不在合适的空气湿度范围内，系统会自动发出报警。本设计具有控制方便、组态简单和灵活性大等优点。【关键词】单片机;湿度传感器;ADC0832 数模转换Based on SCM humidity control system design[Abstract］In daily life， suitable air humidity beneficial to people's health. In industry ， chip encapsulation ， equipment maintenance and factory assembly, etc， all need in appropriate humidity to work. This essay analyzes the humidity of the air， the humidity control system constituted by single—chip microcomputer and humidity sensor collect the data of the environmental humidity and deal with it。 This system can be aware of the change of the environmental humidity timely and accurately by measure absolute humidity， absolute humidity measured by system will be compare with the presupposed upper limit and lower limit 。 if the environmental humidity beyond upper limit or under lower limit,this system will give an alarm.this design's advantage is control convenient，configuration simple and flexibly.［Keywords］ SCM;Humidity sensors;ADC0832 analog-to-digital conversion目录序 言...................................................................................................1第一章 系统的整体设计方案...........................................................21.1 设计内容.................................................................................21.2 系统框图.................................................................................21。3 系统设计方案.................................
