Several. From inexpensive IR sensors to a small console box in the driver's view (no logging or recording, just a readout) like these for bikes: https://www.revzilla.com/motorcycle/...CABEgLzXvD_BwE use two, to single multi-band IR sensors on each corner that are connected to a logger (AiM, VBOX, MoTeC) , about $360/corner plus cables for readout and logging to multi sensor strips for each tire.
I have several folks that added simple individual analog sensors (one per corner) to keep track of balance issues and overheating in general for less than $100 per sensor plus patch cables and the sensors themselves connect to an existing AiM logger.
I've sold Texense strips for big GT cars, but they're around $1080 each corner plus the wiring harness. Just about everything in between. For those with VBOX HD2's, I can provide a complete kit with harness and setup for $2560, 16 temp readings per tire! Crazy.

I posted about them in this thread https://rennlist.com/forums/data-acq...-sale-now.html and https://rennlist.com/forums/racing-a...temp-data.html
The data is really great and when coupled with the TPMS setup, can tell you a TON on how you are using your tires. Plus, you'll have more data than some tire companies!
Like Peter said, there are a number of companies that make sensors. I think the AiM are the best value and the Texense the most accurate in larger operating conditions. There was an interesting article recently that said the current F1 tire has a very, very small operating window for temps and that some of the teams have failed in measuring them accurately and subsequently created poor sim models.
I've done a lot of these sensors and setups - post up if you need anything, have questions, or don't understand the setup at all. If you use the CAN sensors, it can get a bit more complicated and not all folks are well versed in CAN setups. I've done a number and can tell you the pitfalls before you start.

I ran the enduro at IGT at Mid Ohio. I usually start my tires at 21/20/21/22 from left front ccwto right front. I usually end up at around 30 which is my target. But that is after a cool down lap and sometimes after scales. At the enduro i checked pressures coming in hot and they were much more like 32/33 and the car felt very pushy. when i lowered them back down to 30 the car was handling significantly better. On the 2nd pit stop they were up to 31/32 again...lowered to 30 and they were much better. the point is I'm not sure what is really going on temperatures wise with the data I have.

It sounds like you need a TPMS setup more than tire temps. I have few thread, but one here https://rennlist.com/forums/data-acq...for-225-a.html It's $225 and has a CAN out put that can go to AiM, MoTeC, Cosworth, and other data systems with a CAN input. That thread has a great explanation of the data you can collect and how to use it to evaluate performance.
But the tire pressures and the balance issue points to the front doing a disproportionate amount of the work. Until you make a setup change to balance the car better, I would not expect a change in this condition.
M-O is notorious for super high FL wear, too.
