Default O.T. tyre pressure sensors - how do they work?

I understand some new cars can tell you when their tyres need inflating?

How do they work? Is there some kind of pressure sensor inside the tyre that communicates wirelessly with the car's systems?


On mine I believe it uses the ABS sensors to determine if one wheel
(presumably over a period of time) is rotating faster than the others. A
deflated tyre will be smaller in circumference.
