SHT21 as alternative to SHT11
jerryg:
Well unless something has changed it won't work with the davis software it needs to be the ls series and i don't think they make it in that version. I tried one and it would not work, i believe it is i2c only.

Thanks jerryg, I was fairly sure someone on the forum would have tested this sensor at some point. Perhaps something has changed - since I already have the sensor I'd like to test it anyway. Are you able to help me with the pinout?
jerryg:
No i don't have the pin out anymore because it won't work with Davis station so saw no need to keep any info.
dataworx:
Thanks jerryg
I have a dead Davis sensor here, and I have a schematic of the sensor itself, so I'll see if I can strip the protective coating and establish the pinout.

As jerryg points out the sht21 uses i2c serial communication, but the Davis vantage pro 2 uses legacy sensibus communication. The two are not compatible. Although you probably won't damage your equipment your results will be disappointing. If you get the two data sheets side by side it should become clear.
