I'm trying to build a thermometer to measure temperature at a meat thermometer for use in oven or BBQ. Which to use, RTD or simple thermister? Thermoworks sells a thermister probe that goes to 600deg. Has anyone tried this? If necessary, I know how to amplify analog sense with op-amp, and reduce noise. I am aware of self-heating, but it shouldn't be a problem with steady power applied, right? Also, Steinhart-Hart Equation or look-up table?
Thanks
Most thermal sensors aren't food safe. How will you handle that?
Yes, of course. The seller usually states if the prob is food safe or not.
Do you have a link to the seller site where the sensor is listed?
I have a link to Thermoworks probe:
Magnesium melts at 650° - what the Hell are you cooking?
Well... apparently you are not a BBQ enthusiast. One probe goes in the meat, another monitors BBQ temperature. BBQ temp is usually low, though I sometimes like high heat... 400deg or more sometimes.
I don't know how you figured that but . . . WRONG!
What temperature do you usually BBQ at?
Wait - are you one of those Fahrenheit weirdos?

Your comments are disrespectful and off-topic. Keep it up and I will report you.
Disrespectful?
LMAO!
I think that whenever I have seen this mentioned people are using K type thermocouples with a breakout board to make the readings usable. Sparkfun sell such things, as do the other usual suspects I expect.
Thanks. Signal conditioning is one thing, but is it necessary to convert analog sense to digital. Why can't I condition the sense myself?
You probably could, but without knowing much about it, I believe that the signal from the thermocouple is small and tricksy, so unless you are making production hardware where cost reduction is key, it is more common to use existing boards.
The MAX31856 based board is available at Adafruit but it requires digital outputs which are being used by other circuits on my Arduino Uno R3. The MCP9808 board offers I2C which is interesting. Has anyone here used it?
Hi,
No disrespect but the DegC DegF question was posted in jest but as a real question. 
But seriously, and it is important, are you talking C or F Degrees?
Have you Googled:

Getting clarification on the units of measure is never off-topic.
Could be. Let's apply some logic...
weirdos
- a person whose dress or behavior seems strange or eccentric.

The U.S. has 4.25% of the total world population. The U.S., Cayman Islands, and Liberia are the only places left that still use Fahrenheit to measure temperature.
From the perspective of the rest of the world someone still using Fahrenheit can certainly seem eccentric (a weirdo).
I don't see the disrespect. You will have to explain the disrespect (by flagging or using a direct message) if you want action.

Your right, I should specify. Though, outside of a pizza oven, I don't know why anyone would need to go to 600degC for cooking. Most people I know, outside of an engineering lab and still in America, still use Fahrenheit. I understand that we're all eggheads here, so I'll try to use Centigrade from now on.
I've been searching for answers for almost a day. I just copied and pasted your suggestion for a Google search and a article appeared that may be very useful. Thanks. I guess I wasn't using the right words.
