Good work by @wickedbeernut and @PeteKnight 
That code doesn’t make ANY sense (to me 
)?!
I mean, you don’t put that crap in the main loop(), it’s a recipe for disaster! And the vPin only updates if the temp reading is 85.0 OR -127.0. I don’t get it! 
(the complete code referred to is here)
We might be drifting away from topic… But I still believe that a +85.0 °C reading only occurs after cycling the power.
