[Tuya Smart] Tuya Smart Simple Carbon Dioxide Detection Node

Overview

Tuya intelligent air detection node. Adopt MCU docking development solution. Equipped with temperature, humidity, air pressure, carbon dioxide concentration and other sensors to collect ambient air quality~~and record~~. Front: Back: Produced temperature and humidity sensor: APP interface: K1 is the network distribution button, click to perform network distribution operation. Screen color is determined by carbon dioxide concentration calculations. As the carbon dioxide concentration increases, it changes from green to red. For the source code of the microcontroller, please visit https://gitee.com/LC_391338A/tu-ya-zhi-neng_AIR/tree/master Thanks to Lichuang and Tuya for their sponsorship and support. Learn about Tuya https://developer.tuya.com/cn/docs/iot

Known issues: 1. There is an error in the air pressure unit in the APP. 2. The program actually uses the untested rear 64K flash memory of stm32f103c8t6, which is risky.

TODO: 1. Complete the data recording function. 2. Complete the data reading and downloading function. 3. Test the linkage with other Tuya devices.
