Arduino Smoker Temperature Controller

The dallas sensor tops out at about 250 degrees fahrenheit.

Arduino smoker temperature controller.

This particular smoker is electric but the controller will work on charcoal fired ones too. 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. Venting to let hot air out and blowing air on the coals to make them hotter. Wanted to get into glass fusing and decided to build my own digital controller based on a arduino uno.

The universal flame boss supports most steel smokers like the weber smokey mountain pit barrel cooker and weber kettle. The desired smoking temperature along with the desired internal meat temperature is entered on a 4x4 keypad and the controller takes over from there. If you love data insights into how your smoker performs the flame boss 400 might just be your dream smoker controller. Each segment has its own ramp rate target temperature and hold time.

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. You just use the relay to run a fan and motorized damper instead of the heating element. It continuously monitors and pid controls the process until the desired internal meat temperature is reached. Here s a short video of the first time running my temperature controller i built for my smokers.

A thermocouple sensor stuck through. Control up to 3 zones. The final version of the controller program. Each schedule can have up to 20 segments.

Unlimited firing schedules stored on a microsd card. The controller set temperature was 255 f. It then stops the cycle and sends a message that dinner is ready. Pork butt smoking cooking.

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