The Industrial Internet of Things (IIoT) refers to the integration of internet-connected devices and sensors in industrial settings. This technology enables machines, systems, and processes to communicate and share data, improving efficiency and productivity. By collecting real-time data, companies can monitor operations, predict maintenance needs, and optimize resource usage. IIoT is a key component of the broader Internet of Things (IoT), which encompasses various applications beyond industry. Industries such as manufacturing, energy, and transportation benefit from IIoT by enhancing decision-making and reducing operational costs. Overall, IIoT plays a crucial role in the evolution of smart factories and connected supply chains.
