Tire Temperature System Project

mikes603 · 07-21-2014, 08:58 AM

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

Might wanna program the system readings so that you can compare the ir vs probe temp and come up with a rough % difference to see how much it differed from ir vs probe temp

Looks like a cool toy and great idea. I have noticed during auto x the IR handheld temp sensors you have to have it literally a half inch to get an accurate reading. I compared it to a digital gauge that a small probe sticks in the rubber. So you might need to put in a correction factor adjustment to get accurate readings for any given day.

Nice.

IIRC, individual tire pressures are available over the CAN bus. Several CAN threads on this site if you are interested.

How close to the tire do they need to be?

If you drop the screen, and have it produce 4x 0-5v outputs (for pickup by a DL1 or other data acq.) and sell it for under $300, probably could sell a bunch.
