Tire Temperature System

Made this system (I'm an EE) for my car, and other HPDE guys I know. It's to know when your tires are up to operating temp. I thought I'd try and get some feedback here to see what people thought.

Here are the features of the kit:
  • Four IR sensors
  • Narrow 10deg sensor field of view for sampling tire sections
  • Large 1 1/12 by 2 1/2 inch display
  • Weather resistant; sensors can get wet without being ruined.
  • Removable lens cap if they need cleaning or replacement
  • Extra protective lenses
  • Does both fahrenheit and celsius
  • You can adjust the emissivity of each sensor (different materials reflect light at differing rates)
  • Quality harnesses
  • DC supply is designed for difficult automotive environments with large current dumps and voltage spikes

The installation is straight forward. You drill a small hole in the wheel arch for the sensor to poke through. Top center is best to account for changes in tire angle.

I'm aware 3 sensors per tire would be needed per corner to monitor camber load. But that's another kit--one with no display and CAN support for data-logging--and not this one, which is aimed at being sub $1k.

If anyone is interested just send me a PM or email me at mikes at ntisys.com

looks pretty killer. I've had issues with multiple different manufacturers products (At the same speed) being logged on the same BUS at the same time, and having odd errors. How are you dealing with this?

Each sensor has its own unique address on the bus.
