pressure sensor.

how do they measure the pressure in tires.... when moving of course...like hummers for example...they show the pressure in each tire...what do they use?
thanks,

Hi glen,

It’s a small wireless system, a transmitter is housed in each wheel.

I had wondered about this myself . I had assumed it was probably RF, but I had also considere doing a similar thing (in a much slower moving rotation) with brushes kind of like the brushes in a motor.

Hi Heath,

Please tell us more about your ideas!

BTW. Have you recovered from the winds and water yet?
