Sensors are of much importance in industrial automation. They provide real-time data for tracking and controlling the different processes involved. They find changes in temperature, pressure, humidity, or motion and report the same to automated systems for necessary adjustment. This results in making the manufacturing, packaging, and so on more efficient, safer, and superior in quality. The reliability of the system is maintained while reducing downtime with the help of sensors in automation systems, thus optimizing operations and minimizing human error with higher consistency in production.
