Arduino I2CI built a device that reads the temperature from a digital sensor via I2C and toggles a chest freezer on/off to regulate the temperature of a fermentation vessel for home brewing mead. The device holds the temperature between 60 and 65 degrees Fahrenheit with hysteresis built in to prevent rapid toggling. The next phase of development will involve porting the code from an Arduino to a NodeMCU, then having the Node push out the temperature data via REST requests. I am working on a back end in Heroku that will receive this REST request and store the data in a database. There will also be a front end for a user to access the historical temperature data, which will allow for better process control in future fermentation batches.
