Info on WS-2902 humidity sensor please
WA4OPQ:
Does anyone know what humidity sensor the WS-2902 uses?
I'm swapping out my WS-1400-IP sensor arrays with the 2902 units.
I hate the HR202L sensors in the WS-1400s and I'd like to read up on the characteristics of the new sensor.

I don't know. And I don't really want to take mine apart. Maybe someone else will volunteer to do a tear down and determine sensor replacement viability. I too would like to know what humidity sensor is in there. It really does seem to perform much better than the WS-1400-IP series (WS-1001 and WS-1201).
If anyone does take a WS-2902 apart please post pictures.
Another option is to write to Ed @ Ambient Weather and ask him. Maybe he knows or he can find out.
WA4OPQ:
I wrote to Ed. He says: "I am sorry but I am not permitted to share this info. "

Hmmm....I would reach out to Fine Offset the OEM manufacture of all Ambient Weather stations.
I would also reach out to as many branded resellers of these stations. But you would have to know the model of what they call a WS-2902.
Misol
Froggit
Ecowitt
... etc
I don't have a complete list of branded resellers.
But that is a start. Maybe one of them will answer the question.
In any case your original question was about the WS-2902A and if it had a better sensor than the old model. Well it is different alright. I compare my WS-2902A with those older WS-1400-IP around me and I can see the difference. I don't know if it will last longer, but at least it performs better. Highly recommend it.

And with what accuracy does it measure temperaturę - according to the instructions?
