What type of data can some smart sensors communicate to facilitate maintenance before failure?

Smart sensors designed for predictive maintenance play a crucial role in Industry 4.0 by monitoring their own operational state and health. By communicating data about their own performance metrics, these sensors can identify parameters such as temperature, vibration, and various fault indicators. This self-monitoring capability allows for the early detection of potential issues, enabling maintenance teams to perform necessary repairs or adjustments before a failure occurs. Such proactive maintenance not only reduces downtime but also optimizes the lifespan of equipment.

While data about the external environment, production efficiency, and energy consumption could provide valuable insights, they do not specifically focus on the sensor's operational health, which is fundamental for predicting maintenance needs. Thus, the information derived from the smart sensor’s own health metrics is essential for effective predictive maintenance strategies.
