目录

一、主要功能

二、硬件资源

三、程序编程

四、实现现象


一、主要功能

基于51单片机,采用DHT11温湿度传感器检测温湿度,滑动变阻器连接ADC0832数模转换器转换模拟,光敏传感器,采用GP2D12红外传感器,通过LCD1602显示屏显示各项参数,如果红外检测有人靠近,则电机顺时针转动片刻打开窗帘,人离开;如果温湿度超过阈值,则电机转动片刻打开窗帘,用按键替代语音模块,控制窗帘的打开关闭;一个模式切换按键用来切换手动/自动模式,手动模式下,两个按键负责窗帘的开关;自动模式下,则是靠红外,语音,温湿度来控制窗帘打开.并且串口可以远程操控控制窗帘的打开和关闭

二、硬件资源

基于KEIL5编写C++代码,PROTEUS8.15进行仿真,全部资源在页尾,提供安装包。
