Tire temperature IR camera updated (RejsaRubberTrac)

edited September 27 in DIY builds
Just for fun I've added support for the cheaper IR camera sensor AMG8833 to RejsaRubberTrac

So you can build your own IR camera for about €25 per wheel all n all if you buy the two only parts you need from Aliexpress or Ebay.

ESP32 board ca €5
AMG8833 IR ca €20

Currently the source code is here: https://github.com/MagnusThome/RejsaRubberTrac/tree/MagnusThome-amg8833


It looks like this:

And how it looks in Racechrono






Huge thanks to Torben who added support for the cheaper ESP32 boards and Mark for lots of other additions.
RejsaRubberTrac is well tested on track with the Melexis IR camera sensors. The AMG8833 IR camera sensor is tested and works well on the bench but hasn't yet been out on the track for proper abuse :-)

  • PS: How do I add pictures to a post?
  • That looks very nice, thanks for sharing! I've been looking for a tyre temperature solution for a while and this looks likes a setup that is within reach. On the list for the winter projects!
  • If you don't need it running on a small chargeable battery (completely without wires) you can use a cheaper ESP32. I just made a board that contains an ESP32 and a DC-DC converter so you can run it directly on the car battery. The board even autoshuts down when the car is parked so it doesn't drain the car battery. As a bonus it also has CAN bus :smiley:

    This is a complete kit with AMG8833 but you can also use the wider field of view (FOV) Melexis IR camera sensor exactly the same. Just connect to 12V and that's it.

  • Perfect! I like to use the car charge for as much equipement as possible, as batteries alway die at the wrong moment :wink:
