Hello! I'm a total newb to the arduino and I've been trying for some time to find something similar to the max6675 for J type thermocouples. That would be an ideal solution however it doesn't seem to exist. Before I go and invent my own I thought maybe there was another package that I was missing. I do need to read up to 700 F which I believe means that I need to use 12 bit as opposed to 10 bit.
I have a good stock of this type so I'm not interested in switching to K although I'm sure that would make it easier.
Any suggestions?
Thanks!
I see where I went wrong. Thanks! I'm assuming that I can bring the output of the AD8494 directly to one of the analog pins on the controller. Would this give me the kind of range that I need?
No, I don't need that kind of resolution. 0 to 700 F would probably suffice for the range. A resolution of 1 F would be nice but it could go as high as 5 F and it would still be okay.
I'm trying to add temperature control to a BBQ that only has high, medium, and low. It's really a nice unit but lacks the ability to control to a setpoint. I've done this with a PLC already but the footprint is just too big, the cost too high, and the overall system to fragile to handle everything I want it to do. The Arduino should meet all of my needs but there is a learning curve - which makes it a good first project. 
Thanks!
