Digitalisation increases business productivity and competitiveness through improved system optimisation and decision making by using the latest IoT technologies. Currently, digitalisation requires the installation of new, invasive, and extensive systems and as a result, mature industries, such as Oil and Gas, Maritime, Mining and Brewing which widely use analogue (manual) gauges to display critical information, have been slow to adopt. The lack of digitalisation in the Oil and Gas industry alone increases costs by $73 billion per year. EyeSea is a small, wireless, cost-effective, and green powered device which reads analogue (manual) gauges in real-time using a camera and image-processing to replace the manual logging of data. By using existing analogue gauges there is zero process disruption, no change to current methods and ease of verification, which removes major barriers to adoption of digitalisation into industries that until now have remained detached from the latest digitalisation methods.
