I found this cool O2 sensor:  
[https://aliexpress.com/item/1005007088454579.html](https://aliexpress.com/item/1005007088454579.html)

It says in the description it uses UART 9600bps 5V ttl / 3,3 V cmos  
Can XOD use this?  
If so what node?

Hi! Yes, in xod ide, there are nodes for working with uart (there is also a software uart soft node). Using them, you can get data from your sensor to the board.[xod/uart — XOD](https://xod.io/libs/xod/uart/)  
There is also a tutorial on working with uart:
