Sensors play a crucial role in industrial production, as they are not only the infrastructure of a digital society, but also the external organs that connect humans to machines, themselves, and the natural environment. Sensors have functions of information collection, processing, exchange, and storage, and are system level products that integrate sensing chips, communication chips, microprocessors, drivers, and software algorithms. In the process of automated production, various sensors are used to monitor and control various parameters in the production process, such as temperature, pressure, displacement, and speed, converting this information into digital signals for computer processing and understanding.
