摘要生活上,合适得空气湿度有益于人们得身体健康;工业上,芯片得封装,设备得维护以及工厂得装配等,都需要在合适得湿度下进行。该课题对空气得湿度进行讨论,采纳单片机与湿度模块组成得湿度控制系统,对环境得湿度进行数据采集、处理。系统通过测量当前环境得绝对湿度,及时、精确地了解空气湿度得变化,并将当时绝对湿度值与预设得上下限值进行比较,假如不在合适得空气湿度范围内,系统会自动发出报警。关键词:单片机;湿度传感器;DHT11 湿度传感器AbstractLife, moderate air humidity is beneficial to people's health; industrial, chip packaging, equipment maintenance and factory assembly, under the appropriate humidity、 The subject of air humidity research, uses the monolithic integrated circuit and the humidity modules of humidity control system, the environment humidity data acquisition and processing、 The system is adopted to measure the absolute humidity of the environment, timely, accurately understanding changes in the humidity of the air, and then the absolute humidity value with a preset upper and lower limit values are pared, if not in the range of suitable air humidity, the system will alarm automatically、Key words: single chip microputer; humidity sensor; DHT11 humidity sensor目录1 绪论..............................................................51 、 1 目得及意义 ................................................. 4 1 、 2 进展状况 ................................................... 4 2 系统得整体设计 .................................................... 4 2 、 1 设计内容 ................................................... 4 2 、 2 系统完成得技术指标 ......................................... 5 2 、 3 系统构成与框图 ............................................. 5 2 、 4 系统设计 ................................................... 5 3 硬件设计 .......................................................... 6 3 、 1 STC89C52 简介 ...................
