Abstract:
The goal of this research was to create a spectrophotometer that would efficiently detect red dye concentration in water. Creating a low cost, inline design that would be implemented at each lab station in the AguaClara lab was a priority. Red dye concentration was measured by fabricating a photo sensitive sensor that measured the voltage of different standards of red dye concentration. Then, various red dye standards were tested to calibrate the sensor of the system. The goal of calibration was to check in real-time the efficacy of the AguaClara system (or part of the system under study) by integrating the spectrophotometer with the team’s Process Controller software.
