Arduino Smoker Temperature Controller

A thermocouple sensor stuck through.
Arduino smoker temperature controller. The program has these features. Each schedule can have up to 20 segments. The controller set temperature was 255 f. The universal flame boss supports most steel smokers like the weber smokey mountain pit barrel cooker and weber kettle.
If you love data insights into how your smoker performs the flame boss 400 might just be your dream smoker controller. Wanted to get into glass fusing and decided to build my own digital controller based on a arduino uno. Unlimited firing schedules stored on a microsd card. Each segment has its own ramp rate target temperature and hold time.
The desired smoking temperature along with the desired internal meat temperature is entered on a 4x4 keypad and the controller takes over from there. 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. This particular smoker is electric but the controller will work on charcoal fired ones too. Here s a short video of the first time running my temperature controller i built for my smokers.
Flame boss sells two different models so you need to be careful which one you buy. Pork butt smoking cooking. With the charcoal hot and the lid on there are two ways to control temperature. Control up to 3 zones.
Venting to let hot air out and blowing air on the coals to make them hotter. The dallas sensor tops out at about 250 degrees fahrenheit. It continuously monitors and pid controls the process until the desired internal meat temperature is reached. You just use the relay to run a fan and motorized damper instead of the heating element.
The final version of the controller program.
