Arduino Smoker Temperature Controller

With the charcoal hot and the lid on there are two ways to control temperature.

Arduino smoker temperature controller.

Each segment has its own ramp rate target temperature and hold time. Unlimited firing schedules stored on a microsd card. The final version of the controller program. A thermocouple sensor stuck through.

I procured an 8 5 pound pork butt dry rubbed it placed it inside my smoker fired up the controller and 10 hours later at a meat temperature of 197 f i had a beautifully cooked moist pork butt. Wanted to get into glass fusing and decided to build my own digital controller based on a arduino uno. It continuously monitors and pid controls the process until the desired internal meat temperature is reached. Flame boss sells two different models so you need to be careful which one you buy.

Each schedule can have up to 20 segments. The desired smoking temperature along with the desired internal meat temperature is entered on a 4x4 keypad and the controller takes over from there. You just use the relay to run a fan and motorized damper instead of the heating element. This particular smoker is electric but the controller will work on charcoal fired ones too.

The controller set temperature was 255 f. The dallas sensor tops out at about 250 degrees fahrenheit. Control up to 3 zones. The flame boss controller learns your smoker so the temperature control is supposed to get better over time.

The universal flame boss supports most steel smokers like the weber smokey mountain pit barrel cooker and weber kettle. The flame boss 400 offers variable speed which helps to control temperatures in rough conditions think rain snow wind as well as any quirks or specific characteristics of your cooking unit. If you love data insights into how your smoker performs the flame boss 400 might just be your dream smoker controller. Venting to let hot air out and blowing air on the coals to make them hotter.

The program has these features.
