The term Internet of Things or simply IoT first appeared on the Web around 2004, but reached the height of its popularity by the end of 2013 (Google Trends, 2016). The Internet of Things (IoT) is a vital universal information network consisting of internet-connected objects, such as Radio-frequency identification (RFIDs), sensors, actuators, as well as other instruments and smart appliances that are becoming an integral component of the future internet. Recently, these search terms have declined in popularity on the general Web, but gained more momentum among various fields. Modern Dictionaries included the definition of IoT as "the interconnection via the Internet of computing devices embedded in everyday objects, enabling them to send and receive data." The idea and concept behind IoT is not a new thing; it evolved from the Machine to Machine (M2M) systems and what a few companies called the Industrial Internet (Lopez, 2015). Currently, IoT applications are everywhere, from smart homes, smart connected cars, smart cities, smart businesses, and smart agricultural environments. This survey is intended to serve as a guideline and conceptual framework for future research to enhance the Agricultural sector with the help of IoT technology and to motivate and inspire further developments. It also provides a systematic exploration of existing research and suggests a number of potentially significant research directions.
