The Internet of Things (IoT) is no longer a futuristic concept—it is now embedded in every industry, from healthcare to manufacturing. Billions of connected sensors, microcontrollers, and cloud platforms are enabling real-time automation, predictive analytics, and smarter decision-making.

IoT systems typically combine hardware (MCUs, sensors, connectivity modules) with powerful software (firmware, edge computing, cloud dashboards). Together, they create intelligent workflows that reduce cost, increase efficiency, and improve the accuracy of operations. This article breaks down real-world IoT use cases, architecture, and what the future holds.
