基于单片机的智能温湿度检测器设计 \摘 要 在现代生活中，人们越来越重视温度和湿度的检测和控制，因为这两个因素也是影响人们生活的重要组成部分。在人们的日常生活中，在家庭环境中，人们也开始随时随地关注温度和湿度，可以说空调和加湿器等物品都是温度和湿度的产物。在工业上，仓库的温湿度更显得尤为重要，因为仓库的物品可能受温湿度影响会变质变化，这就造成对温湿度的时时检测和控制显得极其重要。在农业生产中，现在的大棚种植技术更是离不开对温湿度的严格控制，各种类型的植物在各阶段对温湿度的要求不一，所以大棚内的温湿度要做到适合棚内植物生长和发育就要求对温湿度进行适时调整和改变以促进植物的更好更快的生长。 该课题就是关于两个重要的因素的智能检测设计，设计以51单片机AT89C52和湿度传感器DHT11为核心，通过液晶显示器LCD1602对温湿度进行实时显示，而且本设计还带有报警电路，对温湿度超出预设值的情况下进行报警提示，有发光二级管和蜂鸣器这两种方式进行同时报警和提示。 关键词：温湿度测量；AT89C52；DHT11；LCD1602 Intelligent temperature and humidity detector design based on SCM Abstract：In modern life, there is a growing emphasis on the detection and control of temperature and humidity, because these two factors also play an important part of peoples lives. In the home environment, people also began to concerned about the temperature and humidity can be said that items such as air conditioning and humidifiers are the product of temperature and humidity. In industrial, warehouse’s temperature and humidity is particularly important, because the warehouse items may be affected by temperature and humidity affect the metamorphic changes, which resulted in temperature and humidity from time to time to detect and control is extremely important. In greenhouse technology in agricultural production, is inseparable from the strict control of temperature and humidity, all types of plants in various stages of different requirements of temperature and humidity, temperature and humidity within the greenhouse to achieve suitable shed plant growth and development of temperature and humidity to make timely adjustments and change a faster and better in order to promote plant growth. my subject is on two important factors in intelligent detection design, the design to the 51 SCM AT89C52 and humidity sensors DHT11 as the core, through the LCD monitor LCD1602 real-time display of temperature and humidity, but this design also comes with an alarm circuit, the temperature and humidity exceeds the preset value the alarm, there are two ways l
