I wasn't expecting NOAA precision from this unit but since the typical unaspirated pws has problems with temp. spikes when the sun is radiating strongly on the unit I was curious if this product was somehow better than a typical unaspirated unit. Your results of a 1.5 degree spike as compared to your NIST calibrated temp humidity sensor is pretty good. Do you have any more data regarding these tests? Also, what was the sun intensity when you did these tests, location (latitude), time of year, and what type of NIST temp/humidity sensors were used?
Thanks for any additional data on this comparison. It might shed some "light" on whether this product is worth checking out.

I am at 34.5 latitude.... in South West Oklahoma.... Sun...a plenty....
I'm sorry I didn't do a more scientific, and therefore more believable review for this --- I simply had a NIST temp/humidity sensor that I placed at the exact spot as the weather station. Now, one can argue what exact means... Because I didn't put up another mast for the comparison temp/humidity monitoring.... That said, I basically put this NIST sensor where the station was, and monitored its data for a couple of days. Of course, I have the logs from both systems that I could extract and post... that might take a bit since NEITHER system allows me direct access to the darn logs.
So, I do have the evidence to back up this unscientific comparison I did --- if I can get the information out of both systems.
I will have to put the sensor back out with the station and maybe do some screen shots of the two together....
I would be happy to do that so we call can see the numbers.
Really, I did the test to see how good or bad it was when compared to a known calibrated sensor. In this case NIST temp it +/- 1deg (and my model claims +/- 2deg) My thinking was, well, that sure is really close so under normal considerations I wasn't too worried it was reading as bad as some other makes and models I hear about.
So far though, this particular model, my only real complaint is the 4" display on the console. There is PC software that reads it directly via USB which gives much larger of course, but it's limited to just that... No trending unless I review the captured data using the PC program (SD chip I added to console is where it saves all the data NOT computer which would be better).
The SD chip is not visible except to their PC program unless I remove and plug directly into computer.
This display limitation for me is no big deal but if I wanted to view it from the other side of the room... that's just not going to happen. No larger consoles available, and from what I can tell, despite the fake coloring others are using, their screens for this function are better, but still not idea.
I digress from the topic however...
I'll see if I can extract the logs in some way of both systems for direct comparison... If not, then I'll see what I can do that would substantiate my claim more than "just cuz I said".... I think perhaps some random screen captures at various times noting sun intensity might go a long way.
