TweetABrew - An Arduino Project
This project is uses the DS18B20 temerature sensor to moniter a home brew during the fermentation stage. It sends tweets at specified intervals or when they temp is out of specified range. That way you can adjust the temperature to make your yeast happy. Happy yeast makes for a better beer!
In the future, I would like to get a mini fridge so that TweetABrew can adjust the temperature automatically. It currently only has one temperature sensor on the OneWire bus. It would be interesting to add another and monitor the internal temperature of the wort as well.
