In a recent article on the website, Shanghai Daily, smart manufacturing and its impact on industry is discussed. Internet-connected sensors, a major facet of the emerging internet of things, is allowing for more efficient machines, lower costs, and more accuracy. Maintenance sensors are now able to monitor machines and robots through sound and provide quick and accurate diagnostics. New scanners are able to read color codes and store large amounts of information. Large industrial upgrades to enormous machines, are now identified by small sensors. In what other ways may these sensors be put to use? How can color coding be used in other functions? Will color coding replace bar and QR codes?
