Smart manufacturing, also known as Industry 4.0, has been transforming the manufacturing industry with the integration of cutting-edge technologies like the Industrial Internet of Things (IIoT), artificial intelligence (AI), and machine learning (ML). IIoT is a network of interconnected devices, sensors, and machines that communicate with each other to improve operational efficiency, productivity, and quality control in manufacturing. However, the integration of IIoT devices into the existing manufacturing infrastructure can be challenging. This is where the IIoT Gateway comes into play.
