🚀 STEM教育：轻松实现空间站数字大屏系统！

步骤1 前言

之前做了一个项目【Mind+ Python】基于Pyecharts + Flask + Pinpong 智能家居数字大屏系统，所用的知识对于新手老师来说不是很友好！去年9月份蘑菇云科创教育就面发布向中小学物联网教学解决方案，推出了三款不同方面科学探究实验软硬件工具，它们分别是：SCI采集模块、云雀气象仪、Mind+物联网可视化面板。如今大半年过去了，Mind+的物联网可视化面板终于可以用上了（真香警告⚠）。

笔者之前用过Onenet view2.0平台（组件较少，开发难度对新手不太友好），

和Onenet view3.0平台（组件丰富，门口较高，数据解析太麻烦，重点需要钞能力?）

现在mind+数据可视化面包的开放，让我们做数据可视化平台如鱼得水，如虎添翼。那么这次就用它来做一个【空间站数字大屏系统】

步骤2 准备阶段

请各位老师确保自己的系统环境是否正确：

1： Mind+1.8.0版本+

2：SIoT V2版本+
