A new generation of advanced smart sensors will become the heart of industrial automation. "Smart Factory" refers to the digital factory, based on the use of Internet of Things technology and equipment monitoring and control technology to enhance information management and services, a clear grasp of the production and marketing processes to improve the controllability of the production process, reduce production line manual intervention, real-time correct To collect production line data, as well as a reasonable production plan and production schedule. Technologies that smart factories can implement include load cells such as wireless sensing, control system networking, and industrial communication wireless. Quick and direct measurement and online control of certain product quality indicators (eg viscosity, hardness, surface finish, composition, color and taste). The integration of smart sensor technology will be able to very well solve the above problems. Sensors are widely used in all aspects of industrial production sensors need to be monitored and the data back to the control center in order to timely intervention of abnormal nodes to ensure the normal operation of industrial production. The industry generally believes that the heart of industrial automation is the new generation of advanced smart sensors that keep the product line up and running, connected to high-performance programmable logic controllers (PLCs) and human-machine interface (HMI) systems through low-latency and real-time networks. Of course, for the manufacturer, time is money. As long as the manufactured product can reach the specified quality level, the production line will run continuously as fast as possible, and the importance of the smart sensor is highlighted. At present, smart sensors, as the most influential and promising high-tech in the 21st century, are attracting the attention of the electronic information industry at home and abroad. The Optical Industry Development Association (OIDA) predicts that smart sensor sales in the international market will grow at a high rate of 20% per year, and smart sensors will play a more important role in the industrial automation era. At present, the industrial production is indeed shifting from a large scale to an automated one. However, with the continuous commercial deployment of the Internet of Things and cloud platform applications, the automation in the industrial field has been upgraded to a higher level Trend, that is, intelligent production.
