Presence sensors detect the presence or absence of specific components at various points in the assembly line. These sensors can use different technologies, such as optical, capacitive, or inductive sensing, depending on the specific requirements of the application. For example, optical sensors can detect the presence of a component by detecting changes in light reflection, while capacitive sensors can sense the proximity of a conductive material. By integrating presence sensors into the WPAN, the factory can implement a robust quality control system that minimizes the risk of errors. If a component is missing or misaligned, the sensor can trigger an alert, halting the production line and preventing further processing until the issue is resolved. This helps to ensure that all products meet the required specifications and reduces the likelihood of defective products reaching the customer. Presence sensors are particularly useful in high-volume manufacturing environments where even small errors can have a significant impact on overall quality and efficiency.
