The Industrial Internet of Things (IIoT) refers to the application of Internet of Things (IoT) technology in industrial settings, connecting machines, sensors, and systems to collect, analyze, and act upon data for increased efficiency, productivity, and decision-making. It's a key component of Industry 4.0, the fourth industrial revolution. [1, 2, 3]  

• Connected devices: IIoT utilizes smart sensors, actuators, and other connected devices to gather data from industrial processes. [2, 4]  
• Data collection and analysis: Data is collected, analyzed, and acted upon to improve operations and make better decisions. [2, 4]  
• Enhanced efficiency: IIoT enables companies to optimize operations, reduce costs, and improve product quality. [2]  
• Improved decision-making: Real-time data and insights enable faster and more informed decisions. [2]  
• Increased productivity: By automating tasks and optimizing processes, IIoT boosts overall productivity. [2, 3, 5, 6]  
• Examples of IIoT applications: IIoT is used in various industries including manufacturing, energy management, transportation, and logistics. [4, 5]  
  
  

How IIoT differs from consumer IoT: 
While the consumer IoT (IoT) focuses on smart devices for personal use, the IIoT focuses on industrial applications, with the goal of improving efficiency and productivity in industrial environments. [1]
