    Does anyone have an idea about how these work?
    would be interested in getting a couple of sensors to play with but how to communicate with them.. is it a standard protocol.. is there a cheap easy way to create a base station for the wireless networks to communicate with?
    Theyre an interesting feature for me and would like to play around with them =]

    Thanks for any useful insights!

    im not sure exactly how they work. I do know they sell aftermarket monitoring systems that replace the valvestem cap and Bluetooth the data to a receiver. I haven't really payed attention to a car that came factory with them to see if they work the same way. I know the system I installed was Bluetooth well, because the package told but I confirmed it with my cell phone.

    This looks like a good overview.

    @adamclark - Have you got a link to these? never heard of them.. sounds pretty nifty
    @tracecom - Useful link, thanks!
    I found a kit on microchip for TPMS development [here], and general google searching seems to imply a standard TX/RX system, with a unique serial ID thats "taught" into the RX Processor.. Technology/Content.aspx

    The definitive option would be to go to a local garage and ask them about TPMS sensors.. they may say they just buy universal and then have to reinitialise the local electronic unit on the car.. iunno.. thought id ask here as the collective intelligence is quite impressive!
