From ancient times to the present, the agricultural process has been one of the most important human needs, and population growth forces farmers to produce more or consume less resources. Agriculture faces numerous challenges, such as resource scarcity and climate change, and needs to produce more food in both quality and quantity. Advances in IoT technology and its data analytics have enabled new solutions to address these complex challenges. Therefore, the aim of this research is to identify the applications of the Internet of Things in agriculture using a descriptive-analytical method and to collect information in the form of documents.The term "Internet of Things" refers to an object (anything that has volume and occupies space) or virtual data and information that has the ability to be identified and integrated with communication networks. The results of the research indicate that the most important applications of the Internet of Things in agriculture are: optimizing energy consumption, increasing production, reducing costs and financial efficiency, preventing environmental problems, etc.
