Hello! Can this DO (dissolved oxygen) sensor be still programmed in an Arduino nano??
xygen) sensor be still programmed in an Arduino??

Posting a link to the datasheet of the sensor would help us a lot.
What do you mean by "still be programmed in an Arduino"?
Most of the dissolved oxygen sensors I've come across in waste water and environmental monitoring, are electrochemical cells with a limited lifetime, and electrolyte, and a membrane that have to be replaced.
Sometimes, the whole cell is replaced rather than being maintained.
What they do need, is regular calibration which where the Arduino could come in.
For proper calibration, you need the temperature of the water to be used as the calibration standard. For acceptable calibration, especially reporting results to authorities, rather than own use, you calibrate at zero % dissolved O2 and 100% O2.
You get 100% saturated O2 water by bubbling air through an aquarium diffuser and the 0% water is achieved by chemically removing all the dissolved oxygen using sodium sulphite and a cobalt catalyst.
I doubt that this is what you want to do and there may be easier methods. However, for reliable results, say for fish farming or environmental damage, regular checks are needed.
For anyone who's interested, the gold standard for dissolved oxygen determination is the Winkler method, involving a chemical reaction and titration.

Wish I'd seen that earlier.
Won't waste any more time on it.
Explain what you want to program? Your question is the same as saying the person with the red maybe blue shirt went that way, find the person.
