First post here :-)
I'm planning to build something similar to this: http://www.amazon.co.uk/Mastrad-Meat-Jam-Thermo-Sensor/dp/B000W02F0G/ref=tag_tdp_sv_edpp_i
However mine will be much more awesome as it will have wifi and a hundred other unnecessary features, the output/interfacing etc.. I'm fine with but the temperature probing end I want to make sure I've covered all the bases with, so just looking for confirmation that I'm not overlooking anything with specs of this component.
My questions relates more specifically to the temperature probe end of the project. I'm basically looking at something similar to this http://www.picotech.com/pt100_sensors.html#insertion (expensive) or this: http://www.sparkfun.com/products/251 (the right price :-) )
I'm thinking:- The range will need to be 0-300°C. (most home ovens don't go much above 260ish, mine doesn't anyway) Accuracy ±1°C or less won't kill my kids when the roast is on the plate. The cable will likely need to be PTFE(Teflon) or similar to stand up to those temperatures (No cables melting to the oven!). Stainless steel for the probe should be perfectly food-safe. A metre long cable will be fine.
Is there anything else I'm not considering here for the temperature probe itself? Also if someone has a probe they could recommend that they have used with Arduino before in similar circumstances I'd be keen to hear about it.
