Development in sensor technology is strongly connected with the progression of manufacturing processes and their demands. For integration in advanced manufacturing processes that follow Industry 4.0 guidelines, smart sensors are preferred. Smart sensors enable self-control and self-calibration of components and can, in connection with soft sensors, form reliable sensors systems. Such systems can in a case of a hard sensor failure either reset its software or enable an adequate soft sensor to temporarily take its place. In conjunction with the use of machine learning, those reliable sensor systems enable introduction and viability of autonomous manufacturing processes in which people only occupy supervisory positions.
