esp8266 通过arduino使用aliyuntosdk如何将两个温湿度传感器（第一个dht11 温湿度传感器(引脚为D4)，第二个dht11 温湿度传感器(引脚为D7)）分别传入阿里云物联网平台的两个设备中并且将两台设备的数据打印在串口和0.96 存显示屏 （驱动 ssd1306，SCL D1 ,SDA D2）每隔一秒刷新发送一次数据并刷新一次显示屏，给出完整代码请仔细想想，不需要topic

需要注意的几点：

1. 代码中使用了两个DHT11传感器，分别连接在D4和D7引脚上，可以根据实际情况修改。
2. OLED显示屏使用了SSD1306驱动，连接在D1和D2引脚上，可以根据实际情况修改。
3. 需要将WiFi连接信息、阿里云物联网平台参数、DHT传感器信息等修改为实际情况。
4. 代码中使用了阿里云物联网平台的SDK，需要在Arduino IDE中安装AliyunIoTSDK库。
