BBQ Probes for the Perfect Steak



  • Hi All,

    I am developing a BBQ Sensor that will set a timer for each probe and tell me when to turn it over depending on what I am cooking (i.e 135F = rare, 2 minutes side one and 2 minutes side 2). Any idea if anyone has developed something like this already? I found the smoker files but I am BBQ fellow not a smoker.....

    Thanks



  • I have something like this for a smoker. A smoker arduino sketch could be easily modified to do what you want?



  • Yes anyone have developed something like this, Price US$30 so it's not worth doing it yourself, unless that you really want to do it yourself

  • @alowhum all help greatly appreciated



  • Hit post to quick sorry, my plan is to have 4 probes each on a timer. Press the button and put on the steak have Alexa tell you to flip after 2 minutes for rare and the another 2 minutes and she will tell you done with a temp of 125f.....



  • What you should look at is the Adafruit_MAX31855 library Then buy a K-type sensor device online.

    https://github.com/adafruit/Adafruit-MAX31855-library

    You can also use the cheaper Max6675. Watch the voltage it uses.

    You'll have so search a bit, but you can also buy meat-probe style K-type sensors at Aliexpress.

    This code may be of use:
