8 K type thermocouplers to Arduino to Can bus....

Projects General Guidance
1

I've found several Arduino TC controller boards that will work nicely for my project. But, I need to get the signal(s) to CAN bus. My ECU only accepts CAN for multiple TC's
Any ideas/advice on the parts/boards needed? OR..if this is even possible..

Thanks, Dave

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

Can you please tell us your electronics, programming, Arduino, hardware experience?

Canbus is not a simple plug and play system when it comes to designing especially to ECU.
What ECU?

What do you know of the original device/system that fed the the T/C canbus signals?

What temperatures does the ECU require?

Each CanBus device on the Bus has its own Address and priority status.

VERY LITTLE/BASIC ONLY. ARDUINO HAS NEVER CAME UP UNTIL THIS PROJECT..

ALL I UNDERSTAND ABOUT CAN IS THE HIGH/LOW SIGNAL, PRIORITIES AND THE LAST DEVICE HAS TO BE TERMINATED WITH A RESISTOR..
THE BOX IS CALLED MEGASQUIRT. I CAN RUN 1 OR 2 CONDITIONED TC SIGNALS TO THE ECU FOR DATALOGGING, BUT TO RUN 8, I CAN ONLY INPUT THROUGH THE ECU'S CAN BUS PORT. MEANING, I'M ASSUMING, ALL SIGNALS WOULD HAVE TO COME OUT OF 1 CAN BOARD. I HAVEN'T FOUND A CAN BUS BOARD THAT WOULD HANDLE 8 TC'S

What do you know of the original device/system that fed the the T/C canbus signals?

THIS IS NEW PROJECT, NOTHING HAS EVER "RAN"...I HAVE 8 THERMOUPLES AND THE ECU WHICH REQUIRES A CAN BUS INPUT..I'M TRYING TO GET THE TWO "TALKING"

What temperatures does the ECU require?

MOST AUTOMOTIVE ELECTRONICS HAVE A MAX OF 150* I'D ESTIMATE

Each CanBus device on the Bus has its own Address and priority status.

I UNDERSTAND...THAT'S WHY I NEED THE ARDUINO TC CONTROLLER TO INTERFACE WITH A BOARD/ADAPTER/CONVERTOR THAT WILL OUTPUT A CANBUS SIGNAL(S) DIRECTLY INTO THE ECU..

Thans.. Tom.. :slight_smile:

I've pursued this for a month now and finally realized I should be asking Aduino people if I needed answers about Arduino.
I was hoping somebody would say "Hey, I just did that set-up !! Here's how I did it"
I know - I know.....
But anythings possible lol

Thanks for your time.....Dave

Hi,
You can use an Arduino with CanBus, use it to obtain your temperature readings, then output to a CanBus shield or breakout board.

If you google

arduino canbus shield
arduino canbus tutorial

This site has good information on their shield

https://learn.sparkfun.com/tutorials/can-bus-shield-hookup-guide

I have used this unit below to work with industrial sensors, but not ECU environment.

It does not mount on top of the Arduino, so you have full access to the other pins for your T/Cs.

I hope this helps.
