以上代码基于FreeRTOS操作系统，在CubeMX中生成的基本工程基础上进行开发。其中，DHT11_Read_Data函数通过DHT11_Read函数读取温湿度传感器数据，并将读到的数据存储在temp_data结构体中。Send_Temperature_Data_To_Yeelink函数将temp_data中的温度数据发送到腾讯云的Yeelink平台。SIM800C_Init初始化SIM800C模块，SIM800C_Connect_To_Network连接到网络，SIM800C_Connect_To_Internet连接到互联网，SIM800C_Connect_To_Server连接到腾讯云服务器，SIM800C_Send_HTTP_Request发送HTTP请求，SIM800C_Disconnect_From_Server断开与腾讯云服务器的连接。
