Quick question to you guys, I wanted to monitor grill temperature remotely, and took one of the probes from my grill thermostat and used a meter to see the resistance change on it. Is there a way I can use that in my AI on netduino plus? or do I really need to get one of those thermocouple amplifiers?
The rest of the plan is pretty simple, I have one of those wireless shields (forgot the name) and an app on my computer that would get the info and write it into spreadsheet which is saved to cloud and reported on my phone. I can also update parameters on the spreadsheet and have the app on my computer adjust the speed of fan.
How does that sound?

Offhand, it sounds like a good idea. What's cookin?
It depends on what the resistance was. Can you drive it with 3.3v and get a reasonable set of values back?took one of the probes from my grill thermostat and used a meter to see the resistance change on it. Is there a way I can use that in my AI on netduino plus?
There are 10 types of people in the world... Those that can understand binary and those who can't.

Yea, i'm going to try that right now, so we can only use 3.3V on the analog pins? not 5v? I better do some reading before I burn this thing.
Had this idea as I was smoking a turkey for thanksgiving. I do briskets and chickens often and if I do more than 2 hours roast/smoke I tend to get a bit anxious and worried... Also had one incident where I ran out of coals and didn't know about it. So, this way I want two probes to return values for me, one from the meat and the other from the grill. I have a small motherboard fan I will be driving as well, which will control the amount of air that gets into smoker (big green egg). And of course doing this from my windows phone was an easy bonus, I figured i'll just have an app on my computer update a spreadsheet on my skydrive and i'll see the changes on my phone. No need for a webserver or anything like that.
