I have an Arduino Yun and I brew beer.
I would like to log the temperature of the beer at all time during the fermentation process (final stage). This means the thermometer would have to remain in the beer during this time (10 days). The temperature would be < 40 degrees Celsius (probably around the 20 degree mark).
Question: What temperature sensor would be best suited to this task?
It must be:
- Food grade
- Can be used in alcohol for extended periods
- Can be hooked up to Arduino (i.e. add a library and ready to go)
