I mean it’s magic right? It’s gotta be magic. How would they even be powered? Or connected to anything? You’re telling me they just sit inside a tire and know shit and communicate it?

You ever have one of those flashlights that you shake back and forth to charge it and it lights for a couple minutes and then you have to shake it again? TPMS sensors work kinda like that. That movement of the tire helps them to charge. They talk to the car’s computer using a small, low-power radio.
