IIoT means connecting industrial equipment – machines, sensors, meters, and controllers – to networks so their data can be monitored and acted on remotely. A factory fitting vibration sensors to its motors to detect early signs of bearing wear before they fail is using IIoT.
IIoT differs from consumer IoT in its requirements. Devices must survive wider temperature ranges, handle vibration, integrate with legacy field protocols (Modbus, RS485), and operate reliably without maintenance for years.
- Predictive maintenance – sensors detect anomalies in equipment behaviour before failure occurs
- Energy monitoring – sub-metering by machine or process supports ISO 50001 compliance
- Remote monitoring – unmanned substations, pumping stations, and remote infrastructure monitored centrally
- Process automation – sensor data triggers control actions without human intervention
- Legacy integration – gateways translate RS485 and Modbus into MQTT for modern cloud platforms
