BBQ

Purpose

This project is to control an offset barrel BBQ smoker equipped with a fan (DIY addition).

The control logic switches a fan on and off, and the thermocouple provides sensing input.

Building your own

You will need:

• an offset barrel BBQ smoker. e.g. (Chargriller Super Pro with the firebox addition)
• a metal bucket with a 100mm hole drilled into the bottom
• an arduino
• MAX6675K thermocouple amplifier + K-type thermocouple
• Adafruit Motor Control Shield (v1)
• A 12v fan - a 100mm PC case fan can work, however for faster temperature rise use a 100mm inline 12v bathroom extractor fan + metal ducting.
• 12v powersupply

Questions

Q) But this only brings the cooking area to 110c, surely that is too cold

A) For low and slow cooking, 105c is perfect... You can shove a piece of meat into the smoker for 4 hours (on top of a water pan for condensation) and let it turn into some of the best meat you've ever had
