internal tire pressure sensor on a road bike
DiTBho:
How would you build an internal tire pressure sensor on a road bike?
it must be
- internal tire
- digital out
- able to measure { 5 .. 8 } BAR pressure
- installed inside the rim, under the inner tube
- or on the valve that is used to inflate the inner tube. In this case, it will be installed on a spoke?
- avoid Wifi, if it's possible
first problem is: how to communicate the data if the sensor is inside the wheel and this rotates on a hub?
how to decouple the wheel and hub by sending the data to the computer that I will install on the bike frame, approximately where the water bottle is mounted.
Mumble ... :-//

Have you looked at automotive TPMS modules ?

thanks, good keyword to Google for :D

I've always found bike tire pressure to be pretty obvious to the rider, you can feel when you have too much or too little. Maybe it's different when the bike is heavier, carrying a motor and battery?
mikeselectricstuff:
If your valves are compatible with car tyres, theer are also external TPMS sytems that have a sensor in the cap
