Introduction to Internet-of-Things (IoT)

Ambika Nagaraj

Abstract

The sensors are tiny devices used to sense the environment or track any object of interest. These are self-configuring devices aiding by minimizing human efforts. Intelligent sensors aggregate resulting in IoT segments. They convert the present reality variable estimated into a digital information stream for transmission to a gateway. Internet of Things (IoT) applications used for city foundations, plants, or wearables utilize enormous varieties of sensors gathering information to transmit over the Internet to a local, cloud-based, and figuring asset. The chapter details the architecture and working of IoT, applications, use cases, challenges of the technology, and future directions. It also highlights the essence of sensors in building an IoT device.
