I have always wanted to make an IR line scanner over each wheel.
Then as the tire rotates, you get a complete temperature map in near real-time.
You would see flat spots, or incorrect suspension setups that way.
What temp sensor is that?
Arduino based?

1) The lens is made of a special plastic made for just this application, it has a passband of the IR freq range used.
2) "You can adjust the emissivity of each sensor (different materials reflect light at differing rates)"
