智能温湿度监测报警系统设计 摘要：温湿度是衡量温室大棚的重要指标,它直接影响到栽培作物的的生长和产 量,为了能给作物提供一个合适的生长环境,首要问题是加强温室内的温湿度的检测, 但传统的方法是用湿度表、毛发湿度表、双金属式测量计和湿度试纸等测试器材，通 过人工进行检测，对不符合温度和湿度要求的库房进行通风、去湿和降温等工作。这 种人工测试方法费时费力、效率低，且测试的温度及湿度误差大，随机性大。在某些 科学研究单位或实验室、生产车间，经常需要将环境的温度控制在某一定范围。采用 电子电路实现对环境温度的控制，其关键是能将环境的相对温湿度转换成相应的电信 号，需要用到温湿度传感器。因此我们需要一种造价低廉、使用方便且测量准确的温 湿度测量仪。该设计即是针对这一问题,设计出了能够实现温湿度自动检测,显示上下 限报警等多功能的温湿度监测控制系统。 关键词：单片机、温湿度传感器、智能。 Intelligent temperature and humidity monitoring alarm system Abstract: Due to the temperture and the humidity is very important in the industrial and agricultural production . Such as canopy planting, granary management must ensure accurate temperature and humidity monitoring .This system according to the use of AT89S52 SCM performance and development situation of the comparatively detailed introduction, this system USES of the temperature and humidity sensor DHT11 do the performance of simple description. On the part of the circuit are introduced one by one, and finally realize the system hardware design, draw the circuit principle diagram. In the software design completed each function module flow chart, and according to the design requirements for function of the realization of the need after repeated simulation operation, debugging, modify, simplify, finally draw a complete set of software system. Topic main task is to complete two environmental temperature and humidity test, and can through the key set temperature and humidity on the floor, more than the lower limit, the system, such as LED light alarm. After the design of the system has good performance and easy to operate, and other advantages, realize the temperature and humidity of the display, alarm functions. Keywords: singlechip、Tenmperature and humidity、intelligent. 目 录 前言1 第1章 绪论2 1.1 课题的意义和目的2 1.2 课题的研究内容2 1.3 课题的任
