Internet of Things

Abstract

Internet of things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. It has three layers. First layer is data acquisition through sensors and actuators, data transferring using different devices and last is data analysis with different analytic techniques. In this chapter, a conceptual overview of internet of things is mentioned. Different sensors and actuators which are responsible for data acquiring are described with their specification. Networking devices which are responsible for transferring data from sensors to server are also described with their applications. Data analytics techniques like descriptive, predictive, and perspective are also explained. Internet of things is now proven as boon for agriculture development. In the last section, different techniques are explained that are used in information and communication technique-enabled agriculture practices.
