piBrew - developed by Morgan Stimpson (morgan.stimpson@hotmail.com)

Using a Raspberry Pi to study the fermentation rate of wort or other fermentable liquids.

How To Run It:

```
 Start up your Raspberry Pi
```

 Have Tmux/SQLite3/Python3/matplotlib/? installed on your Raspberry Pi

 From a either the Pi or another computer start an ssh TMUX client

```
 CD to where the program sits
```
```
 Start the program
```

 Deattach from the TMUX session with ctrl-b d

 Answer the initial start up state with "<your answer in qoutes>"

```
 Reattach the tmux session w/ "tmux a"
```

Ctrl-c the program data should be stored

Data Processing

Line Graph -- to show data over time
// Starting to think about other methods to develop

Goal: // - indicates it has been completed

-Produce 1 model-
-Equip a fermentation tank with sensors-
-Let wort ferment into beer.-
-Constantly pull data and store in a SQLite3 database-
-Train on the model to create a generic model.-
-Use the data to predict for the next batch or future batches-
Adjust bounds of lighting alg.
Figure out how to not need to make a new db but only a table
Figure out how to get the last rowID if the pi crashes and needs to restart
Use the last rowId to continue the fermentation db
Create a server to host data
Graph data on the server

Technologies Used:

Python - Programming Language to conduct everything within SQLite3 - Database MathPlotLib - Data viewing Rasbian - OS of the Raspbery Pi TMUX - Run a terminal, start the program, allow for the client to leave the pi and let it run.

Equipment List:

Raspberry Pi 4B: 1a. CanaKit Raspberry Pi 4 Starter Kit 32 GB EVO+ Case w/ fan 8gb Ram Link;
Breadboard: Full size recommended Link;
Wiring: Male to male wriring Female to Female wiring Male to Female wiring Resistors
Lights: 1 Red Light; Hot Indicator 1 Green Light; Ideal indicator 1 Blue Light; Cold indicator
Sensors:

Temperature Sensor
Model: DS188B20 Temperature Sensor
Purpose: To follow the the temperature change of the fermenting wort. The temperatur change affects all following sensors and the data that they will pull from their readings.
O2 Sensor
Model:
Purpose:
Once most of the O2 is gone the yeast stops reproducing and begins the bulk of the fermentation
PH Sensor
Model:
Purpose:
The acidity of the liquid will kill of the yeast and prevent further fermentation
Others // I can not remember at the moment
