Thread: Custom USB tyre pressure monitoring interface

It is not valve sensor for sure. I have this TPMS here at home. It comes with 4 sensors which must be installed inside the tire. I will remove the receiver from my car and disassemble it in order to get the name of the processor which used there as well as frequency of the receiver.

I was able to live with that, but I cant live with doing the same thing to a 250.00 dollar device. Now Im simply going to order the XM adapter and USB adapter from Mp3car.com.

Maybe you can build it for some of use that arent handy. You can tell us how much money it costs for supplies and shipping and how much you will charge for labor, which is determined by you. I also understand that your a busy man, so I wouldnt put a time frame on you, well as long as its not longer then a year, lol. All in all, I dont care how much it costs or how long it takes, all I know is that if I do it myself, I will end up with a useless TPMS.

Unfortunately I don't have the time to build the device for others people, but I'm pretty sure that there are a many people in this forum (like Dejan ) that can help you.

It is cheap, I have one of these but of course not hooked up to PC. Maybe it is possible to play with hardware interface in order to make it work. I think this system may use the same processor as the one for which hardware interface already created.

That was the tpms kit I used in my first attempt to develope the device, but I had to abandon it due to the bad fastening system of the sensors inside the tyre, indeed as a result of centrifugal force exerted on the sensor during the rotation of the tire, the band expands so that at the first braking, the sensor moves also several inches from the original location, undermining the proper wheel balancing.
I had this bad experience during an high speed driving, so my advice is to use only valve stem sensors!

However, the baudrate and the communication protocol of these sensors is not compatible with my iterface.

Yes, Dejan is helping me..... hes the main. Its funny because I so good with fixing things. Fabricating thing though, I just dont have the patience.
