说明：  如果要将此应用项目移植到开发板上，只需要根据此项目的电路图修改管脚，改成我们开发板对应的管脚上。温湿度传感器使用的是DHT11，所以数据口按照原理图内接。温度传感器接口也需要修改成我们开发板对应的接口
(If you want to migrate this application to the development board, you only need to modify the pins according to the circuit diagram of the project, and change to the corresponding pin of our development board. The temperature and humidity sensor uses DHT11, so the data port is in accordance with the schematic diagram. The temperature sensor interface also needs to be modified to correspond to our development board interface)
