The Industrial Internet of Things (IIoT) is the network of physical devices, machines, and other assets that are connected to the internet, which enables them to collect and exchange data. The IIoT is a key component of Industry 4.0, the fourth industrial revolution. The IIoT has the potential to revolutionize manufacturing and other industrial sectors by increasing efficiency, reducing downtime, and improving safety. For example, IIoT-enabled machines can be monitored in real time to identify potential problems before they occur. Additionally, IIoT data can be used to optimize production processes and supply chains.
