| Summary: | Internet of Things (IoT) provides an environment where everything around us is connected and is uniquely identifiable. This pervasive and ubiquitous environment of connectivity can be very conveniently used for collecting information and enabling intelligent decision-making in many applications that we use daily. Use of appropriate sensors in IoT provides capability of sensing any desired type of information from the surroundings including temperature, light, humidity, seismic vibrations, radiation levels, presence or nature of biological organisms, geological features and more. Recent advancements have made it possible to make things (as in IoT) or objects small in size, powerful in processing, and energy efficient for operational longevity. These aspects of IoT are prompting many emerging applications including in the fields of health, transportation, agriculture, energy, and environment. Hence this evolving field of Internet of Things will be interdisciplinary in nature and will certainly provide a platform for individuals from multiple disciplines to work together. This paper presents an attempt to capture the current state of IoT, its emerging applications, the opportunities it offers, and the challenges it poses.
