I am a beer brewer who is looking for a way to monitor the temperature of my beer as it ferments. I have an Arduino Mega 2560 that I was hoping to use. I was thinking to use a probe to dangle in the beer (obviously) which will be connected to the Arduino. Then I was wondering if there was a way that it could log the temperature every 30 seconds onto a computer or if there was a way the use a wifi transmitter in order to log the temperature somewhere into a cloud file.
Does this seem feasible? Could someone recommend a waterproof temperature probe for the arduino that I could use?
If you have the Mega2560 connected to the computer all the time, you could just write the temperature via Serial.
However I suspect the better solution is to log to SD card. (just buy a SD card module (or micro sd))
Note. Make sure you get on that works on 5V and doesnt need external level translation circuitry
They do make thermo wells which solves the safety aspect, they are fairly thin though so I'm not sure if that probe would fit (it doesn't say a size). I guess you could also make your own out of ss tube...
Yes, but you might not need to dangle the probe in the beer. Taping it to the container along with some thermal paste may suffice. I imagine an SD card is the way to go for you, as it absolves you from having a connection all the time - to whatever. It also allows you to review the day's activity at liesure. I'm not sure there is any point in continuous monitoring anyway. I imagine what you are really interested in is the exception to the norm - if any. You might find a GPRS shield that can send alerts by SMS a better option.
I've heard you can make your own waterproof sensors by encasing the sensor in epoxy or acrylic. In this sketch,
I'm sure this probably works but why can't I find the LiquidCrystal Constructor ?
(not that I need it. I can copy & paste if from one my sketches. I was just wondering why it is missing)
