The purpose of this project was to develop a code for a sensor of our choice, in order to measure a variable for 24 hours. For this project, I chose to measure the change in pH of water, as lemon juice was added. Over the course of 24 hours, an acid (pure lemon juice) was variably added to a cup of de-ionized water. A pH sensor was used to track the change in pH. The data collected was used to calculate the change in concentration, which can further be used to determine water flow rates necessary to maintain a constant concentration. As the program is running, the user is able to pull a summary displaying the minimum pH, the maximum pH, and the overall average pH measured from the start of the experiment. From the data collected, I concluded that the pH change was not as sensitive to the addition of lemon juice as I previously thought. This means maintaining a constant system concentration would not require much effort from a feedback system.
