Steve, I did not say that needs a multiplier. It needs Offsets (Add / Subtract). I agree with you, a multiplier that does not make sense.steve wrote:Do you think it needs a 'multiplier' setting as well as an offset? I'm thinking a multiplier probably doesn't make much sense for UV index, but I could be wrong...
mcrossley, this is already entering in the field of invention .... If Steve wants to be kind enough to apply such offsets will be much easier and after a few tests I will find the correct value. I have done the same with solar radiation and now works well.mcrossley wrote:or stick a bit of tape over part of the sensor
What is required is to resolve a failure of these stations: A way to calibrate their variables. And in this, Steve and his Cumulus are very good!
I know it's a cheaper station! (each one purchase the one that can) But I have it running in the most serious and effective as possible. I do not do it just for fun. Otherwise do not bother me to have a website. I came to the computer and saw the station data.
Steve, I just spoke at the chance. And like you said you could do, I convinced me that you would agree with such possibility of refining the values of UV.steve wrote:Indeed. I have to say I'm not convinced of the need for this, or the validity of assuming that other nearby stations have the correct values, but it's easy enough to add, and I've long since given up trying to do only things that I think are correct
For me there are only two possibilities here. Or is there a way to calibrate the solar panel or the panel is useless. What is the advantage of have instruments that measure wrong values?
This sensor I have, measures UV values 4 times higher than real. And I do not solely based on weather stations around me. I cross these values with the predictions of UV from the national weather.
But of course you are who decides what and when to implement. I'm just eternally grateful to you for all you have done!
To all those who think to buy this weather station, here is the information and so can better decide what to do.
