| Popis: | A portable, low cost sensing system is described which interfaces to an electronic tongue sensor. The sensor used is a voltammetric sensor which monitors electrochemical reactions that occur in solutions. The sensor is able to test a range of liquids with different electrochemical properties without any hardware adjustments to the system. The system can automatically adjust for the change in solution properties by performing a routine which uses an auto-ranging feature to determine a current-to-voltage conversion of the sensor data by using a binary search strategy. This eliminates the intervention of the user to modify the system each time a new solution is tested. The effectiveness of the calibration routine was tested by carrying out cyclic voltammetry in two different solutions, 0.1M sulfuric acid solution and the phosphate buffered solution of pH3. The sensor system was able to accurately acquire the sensor data for each solution. |
