After looking for a tire pyrometer, and only finding hardware that looks like it was made in 1985, here is my first prototype for a Bluetooth pyrometer. Cost is around $45 with no probe so far.

The repository is here https://github.com/j...-tire-pyrometer (wiring schematic coming soon).
My plan is to have the phone App store all the readings. At the moment I just have a proof of concept, but if I can find a few more days of free time I should be able to have it working.
If anyone who has experience with pyrometers and recording tire temps at the track could make a wishlist it would help me to get an idea of what features the app will need.
Let me know what you think.
