E.Coli Automation

This project is the development of a faster autonomous alert system for E. coli exceedances. This system would serve to inform people when E. coli levels in Oak Creek water exceed U.S. EPA criteria by posting results on a publicly-accessible website. The system functions by submerging a paper-based litmus E. coli test strip into an enclosed container of water pumped from the creek. A roller mechanism holds the test strip into the sample water for the required 90 minute period. After the test strip reaction, the color sensor reads the color value to determine the E. coli concentration. This data can then be transmitted to a website to inform park staff and the general public of the E. coli levels.
