Industrial IoT (IIoT)
The Industrial Internet of Things (IIoT) is the network of connected sensors, machines and systems in industrial settings that collect and exchange data. It is the sensing layer that feeds analytics, predictive maintenance and digital twins.
IIoT connects equipment — often retrofitted with wireless sensors — to gather data on vibration, temperature, flow, energy and more, then transmits it to edge or cloud platforms for analysis. It underpins condition monitoring, energy management and Industry 4.0 generally. Key challenges are integration with legacy control systems, data security and turning raw data into action.
