DHT11温湿度传感器

基于单片机的DHT11温湿度传感器设计姓名：史延林指导老师：黄智伟学院：电气工程学院学号：20094470321摘要：温湿度是生活生产中的重要的参数。

本设计为基于单片机的温湿度检测与控制系统，采用模块化、层次化设计。

用新型的智能温湿度传感器DHT11主要实现对温度、湿度的检测，将温度湿度信号通过传感器进行信号的采集并转换成数字信号，再运用单片机STC89C52进行数据的分析和处理，为显示和报警电路提供信号，实现对温湿度的控制报警。

报警系统根据设定报警的上下限值实现报警功能，显示部分采用LCD1602液晶显示所测温湿度值。

系统电路简单、集成度高、工作稳定、调试方便、检测精度高，具有一定的实用价值。

关键词：单片机；DHT11温湿度传感器； LCD1602显示第一章：课程构思1.1课题背景温湿度的检测与控制是工业生产过程中比较典型的应用之一，随着传感器在生产和生活中的更加广泛的应用。

在生产中，温湿度的高低对产品的质量影响很大。

由于温湿度的检测控制不当，可能使我们导致无法估计的经济损失。

为保证日常工作的顺利进行，首要问题是加强生产车间内温度与湿度的监测工作，但传统的方法过于粗糙，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。

目前，在低温条件下(通常指100℃以下)，温湿度的测量已经相对成熟。

利用新型单总线式数字温度传感器实现对温度的测试与控制得到更快的开发。

但人们对它的要求越来越高，要为现代人工作、科研、学习、生活提供更好的更方便的设施就需要从数字单片机技术入手，一切向着数字化，智能化控制方向发展。

对于国内外对温湿度检测的研究，从复杂模拟量检测到现在的数字智能化检测越发的成熟，随着科技的进步，现在的对于温湿度研究，检测系统向着智能化、小型化、低功耗的方向发展。

在发展过程中，以单片机为核心的温湿度控制系统发展为体积小、操作简单、量程宽、性能稳定、测量精度高，等诸多优点在生产生活的各个方面实现着至关重要的作用。

DHT11数字温湿度传感器(附1602显示程序)已验证ok

DHT11数字温湿度传感器(附1602显示程序)已验证ok

1、DHT11产品概述DHT11数字温湿度传感器是一款含有已校准数字信号输出的温湿度复合传感器。

它应用专用的数字模块采集技术和温湿度传感技术，确保产品具有极高的可靠性与卓越的长期稳定性。

传感器包括一个电阻式感湿元件和一个NTC测温元件，并与一个高性能8位单片机相连接。

因此该产品具有品质卓越、超快响应、抗干扰能力强、性价比极高等优点。

每个DHT11传感器都在极为精确的湿度校验室中进行校准。

校准系数以程序的形式储存在OTP内存中，传感器内部在检测信号的处理过程中要调用这些校准系数。

单线制串行接口，使系统集成变得简易快捷。

超小的体积、极低的功耗，信号传输距离可达20米以上，使其成为各类应用甚至最为苛刻的应用场合的最佳选则。

产品为 4 针单排引脚封装。

连接方便，特殊封装形式可根据用户需求而提供。

2、应用领域►暖通空调►测试及检测设备►汽车►数据记录器►消费品►自动控制►气象站►家电►湿度调节器►医疗►除湿器应用领域3、接口说明建议连接线长度短于20米时用5K上拉电阻,大于20米时根据实际情况使用合适的上拉电阻4、电源引脚DHT11的供电电压为 3－5.5V。

传感器上电后，要等待 1s 以越过不稳定状态在此期间无需发送任何指令。

电源引脚（VDD，GND）之间可增加一个100nF 的电容，用以去耦滤波。

5、串行接口 (单线双向)DATA 用于微处理器与 DHT11之间的通讯和同步,采用单总线数据格式,一次通讯时间4ms左右,数据分小数部分和整数部分,具体格式在下面说明,当前小数部分用于以后扩展,现读出为零.操作流程如下:一次完整的数据传输为40bit,高位先出。

数据格式:8bit湿度整数数据+8bit湿度小数数据 +8bi温度整数数据+8bit温度小数数据+8bit校验和数据传送正确时校验和数据等于“8bit湿度整数数据+8bit湿度小数数据+8bi温度整数数据+8bit温度小数数据”所得结果的末8位。
