Introduction
The Internet of Things (IoT) has revolutionized industries by enabling smart devices to collect, process, and transmit data. However, many IoT applications require ultra-low-power devices that function on constrained energy sources, such as small batteries or energy-harvesting technologies. Traditional AI models often demand high computing power, making them impractical for these lightweight IoT deployments.
Enter TinyML, a breakthrough technology that brings machine learning to low-power embedded devices, enabling smart applications without relying on cloud connectivity. By deploying AI models directly on microcontrollers and edge devices, TinyML makes real-time AI inference possible on a milliwatt-scale energy budget.
