其中需要根据自己的情况修改代码中的宏定义和变量，如：

- `L610_UART_HANDLE`：L610通讯模组串口句柄，需要根据实际使用的串口进行修改。
- `L610_RESET_GPIO_PORT` 和 `L610_RESET_GPIO_PIN`：L610通讯模组复位引脚所在的GPIO端口和引脚，需要根据实际使用的GPIO进行修改。
- `iotProductId`、`iotDeviceName` 和 `iotDeviceSecret`：腾讯云IoT产品、设备名称和设备密钥，需要根据自己的腾讯云IoT配置进行修改。
- `temperature`：需要根据实际使用的传感器或芯片进行读取温度数据的代码编写。
