Can Temperature Sensing Prevent Milk from Boiling Over?

[I_am_learning]

I don't know about you people, but I often loose my milk, because it boils and spills out, just when I am not looking at it. :)
Is it possible to alarm when it is just about to boil, by sensing its temperature?
My concern is, is temperature a reliable indicator (impurities, varying degree of FAT in the milk, variation in atmospheric temperature etc)
I don't want very precise alarming, but hey, it needs to prove its worth!
(yeah, I do electronics )
Thanks in advance.

What I do when I want to boil water without it boiling over is to set the stove burner low. That way I can walk away and if it does start boiling it won't be boiling very vigorously. It will take longer to boil but at least I don't have to stand there keeping an eye on it.

I'm no chemist, but generally, adding small amounts of sugars, salts and fats to water should raise the boiling point slightly. In an http://van.physics.illinois.edu/qa/listing.php?id=1451" on line, they suggest using a double boiler to prevent the milk from boiling.
