Industrial IoT sensor networks are connected systems of sensors, communication devices, gateways, and software platforms that collect, transmit, and analyze data from industrial equipment and facilities.
These networks are a core part of modern digital manufacturing because they allow machines, production lines, utilities, and infrastructure to exchange information continuously.
Industrial IoT solutions combine sensing technology, communication networks, cloud computing, edge computing, and data analytics to monitor industrial operations. Information collected from sensors can include temperature, pressure, vibration, humidity, energy consumption, flow rate, machine speed, and equipment status.
Wireless industrial sensor networks are increasingly common because they simplify sensor deployment in factories, warehouses, processing facilities, power plants, and transportation systems without requiring extensive wiring.
