来源：互联网发布：windows官网镜像编辑：程序博客网时间：2024/05/16 09:12

1.问题提出

1.1、如何编写温湿度传感器实验程序

1.2、如何编写串口通信代码

1.3、如何利用c#的Serialport去获取串口传输的数据并完成上层应用界面设计

2.功能要求

2.1、设置温度报警值为26度，达到报警值时，红色闪亮，当低于报警值时，停止闪亮，同时，按下按钮，也可以解除报警；

2.2、将温湿度采集通过串口发送到电脑，上层用串口小助手查看，或者用VC等编程语言读取串口数据。

3.实验准备

3.1、IAR 安装

3.2、USB 转串口驱动安装

3.3、ZigBee 仿真器驱动安装

3.4、USBmini数据线、物联网基础实验箱、下载器

4.实验结果

4.1总体设计

4.2实验结果

描述：当温度高于26摄氏度时，Led闪烁警示，按下按键之后，报警解除，Led熄灭

4.3功能模块代码实现
