Revolutionizing Agriculture with IoT –A Review

Agriculture has a significant role in society by providing food and acting as the foundation of many developing countries' economies. With an estimated 9.75 billion people on the planet by 2050, food production must rise to meet the growing demand. It is getting harder to increase food production since there is a lack of fertile land. To solve this issue, increase output per unit area, and achieve the desired outcome, precision agriculture technologies are being used. The Internet of Things (IoT), artificial intelligence (AI), and machine learning are among the smart technologies that are being adopted by an increasing number of industries, including agriculture. Automated irrigation systems can be advantageous for farmers who practice precision agriculture, who can also gain valuable knowledge about their crops and lessen their environmental impact. With the help of these technological advancements, farmers can now more easily manage farming processes. This article summarizes the types of sensors needed for agriculture, the communication technologies used, and various aspects of smart farming. The roles of Artificial intelligence, 5G, and Blockchain in smart farming are discussed.
