IoT in Manufacturing: Driving Industry 4.0 Transformation

The Fourth Industrial Revolution, or Industry 4.0, is transforming manufacturing through the integration of IoT (Internet of Things) technologies. Smart sensors, connected devices, and real-time data analytics are enabling manufacturers to optimize operations, reduce downtime, and create entirely new business models. Let's explore how IoT is reshaping the manufacturing landscape.

What is Industry 4.0?

Industry 4.0 represents the convergence of physical and digital technologies in manufacturing:

• Cyber-Physical Systems: Integration of computation, networking, and physical processes
• Internet of Things: Connected devices and sensors throughout the factory
