The Industrial Internet of Things (IIoT) is the application of IoT technology in industrial settings, gathering and analyzing data for real-time decision-making and predictive analytics. IIoT integrates sensors, software, and machinery with internet connectivity to improve efficiency, reduce costs, and enhance product quality. It’s transforming industries such as manufacturing, energy, and transportation by optimizing operations and revolutionizing processes. IIoT also plays a significant role in healthcare, logistics, and the utility sector. However, implementing IIoT faces challenges including security, integration, data management, and a skills gap.
