Abstract | Smartphone technology provides bountiful opportunities for greater participation in scientific and technological research and monitoring. Digital camera image sensors have been used for the detection, measurement and monitoring of rust, this research extends that capability to the smartphone. It has been observed that as rust content increases in a clean iron sample, red responses decrease proportionally. Green and blue responses quantifiably decrease faster, matching the observed overall reddening as rust proportion increased. Potential noise sources due to the variable texture of the rusted samples had a negligible effect on the results. The effectiveness of this method for the characterisation of a smartphone image sensor response to the amount of iron corrosion is reflected in the congruent validation tests and errors never exceeding 5%. These results demonstrate that the smartphone can be used as a low cost and efficient means of evaluating the percentage of surface rust content. |
