The TT2X Project - Live Tyre Temperature Data - Mike Jackson
After being inspired by other versions of this technology, usually used in Car racing, I decided to build my
own version to provide live temperature data whilst racing / riding on a motorbike.
The TT2X system uses two infra red temperature sensors for reading the front and rear tires,
an Arduino micro controller takes the live data and sends information to the LCD display.

After a successful test (In December!!) on the first prototype, I knew I could develop the project further and incorporate more functions such as a colour screen and data logging functions.

From there on, I produced new 3D design files to build a housing for the larger display and set to work on writing the software to drive the larger screen. I used Google Sketchup to design the parts and then had them printed by Shapeways.com
The sensors are housed in another 3D printed part, again designed from scratch using Sketchup. The housing is then attached to the tip of the mudguard so that the sensor is pointed at the tyre surface.
The current version of the software allows me two ways
of reading the data on the 2.2" screen.
1) The live tyre temperature is shown on an easy to read graphical display, as the temperature changes, so does the colour of the "tyre". Changing from Blue, Yellow, Green and Red as the temperature changes from cold to overheating.
2) The second option is to "log" the data from the sensors over a specified time frame onto a graph. I can setup the graph to provide data over a period of time ranging from 30 seconds to 10 minutes, and then the graph can either restart again or save the plot on the screen for review in the pit. I like this a lot!
I can't wait to try this out on track and see how it performs, and ultimately see
if the data gives me useful information whilst riding the bike.
Watch this space!
