An embedded system powers IoT devices by acting as the brain behind their operations. It combines hardware and software to perform specific tasks efficiently, such as collecting sensor data, processing it, and communicating with other devices or cloud platforms. These systems ensure real-time performance, low power consumption, and reliability, making them ideal for smart devices in homes, healthcare, agriculture, and industry. By integrating microcontrollers or microprocessors, embedded systems provide the intelligence and connectivity essential for IoT functionality.
