The application of sensors in the electronics industry is extremely extensive and vital. As the core component for sensing external information, sensors can capture changes in various physical quantities, chemical quantities or biomass in real time and accurately, and convert them into measurable and processable electrical signals. In the design and manufacturing process of electronic products, sensors play a key role in monitoring and control. From touch screens and accelerometers in smartphones to temperature sensors and pressure sensors on industrial automation production lines, all reflect the importance of sensor technology. They not only improve the intelligence level of products, but also greatly enhance the automation and precise control capabilities of the production process. With the vigorous development of the Internet of Things, big data and artificial intelligence technologies, the application of sensors in the electronics industry will be more in-depth, providing strong technical support for the realization of more efficient and intelligent production and manufacturing models.
