Smoker temperature monitoring for maximum BBQ and smoked meat.
About
Make monitoring your BBQ super easy by using multiple cheap food grade thermistors to measure temperature of meat(s) as well as smoker box. Connect said probes to a simple computer to process signals and then relay data to the cloud, local server or phone.

Parts
I originally looked at using an Arduino w/ESP8266 wifi chip for the analog pins. However it seems that doing dev on a Pi is way easier especially for mDNS, etc. Plus I had previous experience and felt comfortable a Pi would provide a ton of flexibility.
