Not a terribly original project, but spending Saturdays grilling has me thinking I might want to get into more smoking and keep track of temperatures better.
Seems like a semi-simple thing to do with parts like:
- ESP8266 - have one of these spare
- A display would be nice
- An ESP32 with integrated display could be really handy
- K-type thermocouple probes At least 2 - one for food, one for grill. These seem semi-consumable and go bad after awhile, so best to use the pluggable ones
- 2.5mm mono jacks for the thermocouples - I have lots of those
- MAX6675 temperature to SPI interface
- DHT22 for external temp & humidity? Probably overkill
- Waterproof project case?
I can write simple firmware - like my WIFI pumpkin - though getting even fancier with IoT integration could be fun
Something like a PID and a fan could be interesting for temperature control. But all I have is a little Weber charcoal kettle, so that's really over-complicating things. Also I'm not really all that skilled or advanced at the grill yet, so a semi-accurate thermometer would be a huge upgrade as it is 😅
