A National Instruments Compact Rio embedded controller and its software program LabView is used as the basis for this system. A swimming pool model was selected to trial the system due to its similarities with both drinking water and industrial plants. The system monitors the following water parameters: temperature, pH, free chlorine level, oxidation-reduction (redox) potential, total dissolved solids and turbidity. The system controls five chemical dosage pumps, a heating element, an inlet valve, 2 outlet valves, a main pump and a fibre optic system. Currently the system has almost completed its proof of concept phase. The system can monitor water parameters to an accuracy comparable with standard manual techniques and it can control chemical dosages to an accuracy of +/-1.3ml. Tests have been performed using both rated and proportional pump control. Data can be written directly to an Excel worksheet for storage and analysis. The system can publish its display to a webpage which can be accessed for both monitoring and control purposes using a laptop, PDA or mobile phone. Similarly the stored data can be accessed remotely. A fibre optic turbidity sensor is under development using affordable off the shelf components. An optical E. coli detection system using a FRET micro array to detect DNA is being developed in conjunction with Dr. Michael Kane at Purdue University. The aim of this collaboration is to produce a reusable and reliable biosensor capable of detecting low levels of target DNA sequences.
