Base on open source hardware Raspberry Pi Pico W and Embassy embedded (no_std) async facilities
every 5 seconds temperature sensor trigger out async function through channel. And this out function send message to cloud.

异步IO框架Embassy使嵌入式编程更简洁，2022年底embedded-hal-async/embedded-nal-async等trait即将稳定，期待2023有完善的网络协议栈实现。 可以带来快速启动，成本低廉，易于维护等好处。
- 增加关键数据个人云存储功能，比如加密货币的token/密码/日记/语音等
- 在Raspberry Pi Pico W上启动DNS服务，利用云连接做到类似httpsDNS的个人工具
- 在Raspberry Pi Pico W上启动NTP服务，甚至是最新的PTP（us级别的）时间同步
- 其他？GPG？
- Rust embedded 生态
