I received the Johnson A419 Digital Temperature Controller and will be getting a Fermwrap today in the mail (and I will be brewing tonight hopefully).
I noticed that the Johnson model comes with a probe. Do I sanitize this probe and place it through the airlock into my wort?
I currently use a Raspberry Pi with DS18B20 temperature probes to monitor the temperature of my wort, which I store in a database. I sanitize these probes and place it through the airlocks into my wort.
I would not be able to fit both the DS18B20 and the Johnson probe through the airlock as the diameter isn't big enough.
Must I sacrifice my statistical experiment to accomodate the Johnson probe?
On the other hand, is there a way for me to put the Johnson probe through the airlock and then read send the temperatures from the Johnson Control to my Raspberry Pi (Or first to my Arduino and then to my RPi)?
