The System

The whole system is made up so many individual parts. How each of these parts is linked to one another can be seen in figure 4.1 which display the system overview. Everything starts from the user giving input to the computer. The main controller board will then determine a set point for the pH system to achieve. The board will then instruct the actuators to inject certain solution into the pH system to change it to the desired pH. The pH probe will then take the reading from the pH solution and feedback to the main controller board. This will carry on until the pH has reached the set point. At the same time, the red cabbage will change color and feedback to the user whether his health or relationship is being affected. Eventually the user will also make certain adjustment to his lifestyle and change the input.
