This sensor "looks" for anything inside the oven before heating. For example, when you go to preheat your oven the sensors automatically
detect any object in there and will beep at you and also indicate it on the screen. I don't know about you, but I have put something in the oven that was not meant to be there and next time I went to heat it, not realizing the thing is still in there, and moments later I smelled a burning smell and then opened the oven only to find the object burned for good. With this sensor, that would never happen again and this would also be a fire safety feature too!!
