What's changing

The part that reports on itself.

A sensor used to send only a reading. Now it can process the reading itself, detect a gas leak, a failing transformer or a crack, and report only what matters; makers are adding small AI models to it. In AI data centres, connectors carry more data than ever and have become precision products in their own right.
