Title: Grill/Smoker Temp Controller
Post by: briankb on December 12, 2013, 07:15:58 pm

I have a Primo XL cermic grill and the way you adjust the temperature is mostly through the vent at the bottom which allows air into the fire pit.

I have several devices to choose as the host: digispark, digix, arduino uno, raspberry pi, and a beaglebone black.

My goals for the temp controller device are fairly simple and include:

• Read & Display Inside Temp
• Read & Display Meat Temp (option for a 2nd meat probe)
• LCD Display
• Web Server to Display Temps and Allow Adjustments
• Retains Temp Setting after reboot or power failure
• Wi-Fi or other wireless connectivity to allow web server functionality

The first and main goal is for the device to control the on/off state and speed of a small blower that sits inside the air intake on the grill.

I have the following parts:

Which device should I use for this project and where do I start in order to connect the temp probes and ultimately the blower.

it is very rare that real posts get marked as spam so I only find time to look through them every week about - sorry for the delay, the holidays made that a bit longer in this case

Read the probes with this: http://www.adafruit.com/products/269 - or the base chip on it

The DigiX would fit the bill for this nicely - raspi and bbb could do it as well, though you might be more limited with them if you decide to add more sensors, etc later on

Thanks! I appreciate the follow up, late or not :-). I haven't had time to start this other than to order the temp probes and the fan assembly. Hopefully this week or next I can get something put together and report my progress.
