I was playing with the idea of some kind of better controlled or robotized spot soldering with hot air.
It would be nice if the board and component temperature could be measured from a distance.

Found these sensors of Melexis MLX90614.
They can measure from -70 to 380 degrees Celsius.
Costs are (quantity=1)from about €12 (standard FieldOfView 90 degrees) to €40 (FOV 5 degrees) at Digikey.

Of course someone has done it already...
Examples?

Nice part!!
Did you look at the MFR. website for application notes?

There is some info here:
http://arduino.cc/forum/index.ph...

And if you put this in google search:
Melexis MLX90614 application examples

you should have quite a bit of reading to do

(Yes nice part, and its price is good for experiments.)

I was more looking for a construction example of hot air gun with the object surface temperature sensor arrangement.

How to keep the air jet at the measuring spot (as the distance may vary)?
I think I need some concentric design for that. The 5 degrees device can peek trough a relatively small hole.
But sensor has to be kept 'cool', and at (constant) known temperature.
I have seen examples of air or water cooled sensors, but I want to avoid that.

Electronics and software I consider as 'solved' (or solvable).

THat's why it's called engineering!! :)
