Nothing to write home about, but just noticed that Sensirion has increased the typical temp accuracy from 0.3C to 0.2C. https://www.sensirion.com/products/humidity-sensors/digital-humidity-sensors-for-various-applications/

The most interesting aspect of this, is how CW2274 ever learned about this enhancement!! We are impressed Jim!

Just doing some research. I can only assume that Sensirion leaned towards the conservative side when first spec'ing the SHT3x, but now feels this is more typical.

Good catch...... So... +/-....  (.36F) instead of (.54F). Doesn't get much better.

Correction if I did the math right... ;)

No. Davis is designing its VP3 that will knock our socks off!

Why design an new PWS when the VP2 is as good as Davis  will ever get for an cheap build  station. Only better come in over the 1000 buck mark.

The concept of a VP3 has been beaten to death in this Forum. Apparently it is not in the cards. However, Davis does not need to target a price point of over $1,000 to make the VP2 better. An 8" rain collector, an easily replaceable supercap, a color console, a console that can communicate to the computer using bluetooth technology, or the like, so during an electrical storm the connection is not lost which frequently happens to my setup, and make Weatherlink a better software package--not so DOS looking too. All of this should easily be incorporated into a new product, say VP3, without a substantial increase in today's pricing of the VP2. :grin:

If not a VP3,  how about at least a VP2+? (ha,ha)
