How do microwaves with cooking sensors determine when the food is done?

Somebody told me they sense the amount of steam to tell how hot food is but the amount of steam would probably vary according to what you are cooking and if a cover is used. So how does it work?

It's basically sniffing your food It takes advantage of several facts about what happens when food cooks: Most food contains water. Even microwave popcorn. Water will never heat to more than 212 without turning to steam.So most food cooked in the microwave will never get to much more than 212 degrees.

That’s why foods down brown in the microwave: brownness requires temperatures well over 300. Microwave dinners are pre-cooked. All you’re really doing is heating them up.

When they get hot, they emit other chemicals in addition to water So the simplest sensor would be one that detects the presence of steam in the oven. When the steam hits 212, the food is as hot as it’s going to get. The rest of the operation is just boiling off more water, at least until the food is completely dessicated.

And in fact that’s pretty much how inexpensive rice cookers work: once all of the water is boiled off, it’s done. Actual microwave sensors are more complicated than that. They’re looking not just for the presence of steam, but watching the rate at which it grows and then levels off.

They’re really looking for that leveling off. They use a bunch of fancy algorithms and neural networks to try to avoid being fooled, but that’s the gist of it. The newer generations look at things other than water.

They’re basically sniffing the food, looking for odors that indicate doneness. When food gets hot enough it puts out alcohols and aromatic molecules, and those are easily picked up with a sensor that determines the electrical resistance of air. Combining all of those factors is some pretty tricky programming.

It’s actually a pretty good test to do yourself: food cooked in the microwave is done when it smells done. If you can’t smell it, it’s not cooked and it need more time.It’s a lot less painful than sticking a finger into hot food. Popcorn is a little trickier, and there’s usually a separate popcorn button.

Popcorn pops at well above 212: you have to superheat the water inside a popcorn kernel until the shell shatters. They’re looking at specific chemicals put out when popcorn pops, and when that level stops going up it means all of the popcorn is popped. The sensors will get some things wrong, and they try to err on the side of not incinerating your food.

Moisture levels The microwave uses sensors that detect how much moisture is in the air. Sources: sensorland.com/HowPage031.html .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
