开发板：正点原子 STM32F103 精英版

语言：C语言

开发环境：Keil5

**开发板**使用了 LED KEY BEEP  TFTLCD USART DHT11模块 DS18B20模块

## 代码下载：

[码云](https://gitee.com/ikaros-521/STM32_DHT11_DS18B20_show_T-H) [GitHub](https://github.com/Ikaros-521/STM32_DHT11_DS18B20_show_T-H)

## 功能介绍：

1、LED0约2秒一闪，表示程序运行中。

2、LCD和串口显示实时的温湿度，2秒一循环。上面一个temp是DS18B20，下面的是DHT11。%RH 相对湿度，  CEL 摄氏度（ps：不接入DS18B20的话会循环等待）

3、按键都会翻转LED1，KEY1 开启报警模式，KEY0关闭报警模式。（按键10ms一巡检）

4、报警模式下：当温度不低于85摄氏度或者湿度不低于90%RH，蜂鸣器报警。可以通过按下KEY0关闭报警模式。（报警串口会有打印，LCD也会有提示）

# 效果图

## 普通环境

### 普通版main.c

### 升级版

## 哈热气

### 普通版

我这哈了3下

![在这里插入图片描述](https://img-blog.csdnimg.cn/20210425141812267.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0lrYXJvc181MjE=,size_16,color_FFFFFF,t_70)

然后持续手扇风

![在这里插入图片描述](https://img-blog.csdnimg.cn/202104251418503.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0lrYXJvc181MjE=,size_16,color_FFFFFF,t_70)

ok，温湿度降下来了。

### 升级版

## 搓手捂热

手有汗，湿度也上来了

（下图是旧的，仅供参考）

最后本来应该整个打火机的，可惜没有。夹咯吱窝下（仅DHT11 旧图）

最后来个鼻息
