Introduction
Brewers have often been challenged by the complexity of fermentation. It is an extremely volatile point in both the brewing and winemaking process, that is susceptible to temperature, infection, and human error. In order for fermentation to be successful, the producer needs to keep their product at a specific (hard to maintain) temperature for an extended period of time. This temperature is specific to every unique strain of yeast. Failing to maintain this temperature will provide a bad product, wasted time, and a loss of money. For example, the average California Ale Yeast ferments at 67°F. This is a
PCB
The perforated two planed board sized for efficiency and aesthetics. A small board could house all the surface mounted components selected, 96mm x 75 mm. The Power trace lines were set at 0.8mm to ensure enough current flow. The communication trace lines were sized for 0.4mm because the voltage was much lower.
System Software
The internal System is responsible for powering the entire system. This system is responsible for facilitating the peripherals, updating the Web Service API, analyzing the sensor data, and controlling the electrical relay. The internal system software will be running on the Raspberry Pi 3 Model B. This system is responsible for collecting data from the DS18B20 via the 1-Wire Interface. The system also uses the I2C Interface to receive data from the BMP180 pressure sensor. In order to control the the relay, the system uses the internal serial port for the bluetooth sensor on the Rapsberry Pi 3 Model B.
Web Application
The team chose to go with PHP. The team likes the idea of a loosely typed language giving the programmer more control over the code. The programmer can choose whether or not to explicitly type cast or have the interpreter/compiler choose the variable type. PHP is also easily run on a Linux environment using the LAMP stack of development. .Net is only allowed to run on IIS server system. PHP is an open source project with a lot of community support while .Net is created by Microsoft.
