Smart agriculture is an important direction for the development of modern agriculture. Only one mobile phone and one agricultural technician are in charge of controlling a number of agricultural greenhouses. This situation has become a reality with the development of information technology, which has also opened up a new era. The development and construction of smart agricultural Internet of Things technology, to perceive the premise, to achieve a comprehensive network of people, people and things, things and things fully interconnected. In traditional agriculture, watering, fertilizing and fighting drugs depend entirely on the experience and feeling of peasants. And now you can use the various sensor devices based on Internet of Things technology to detect physical parameters such as temperature, humidity, ph, light intensity, soil nutrients, carbon dioxide concentration in the environment, real-time upload Waterdrop mobile Internet of Things cloud platform, technology Personnel can use mobile phones to grasp accurate agricultural data and control agricultural production based on these parameters to ensure that crops have a good and suitable growth environment. With just a cell phone, an agricultural technician can learn about the situation of large-scale crops in real time, grow good vegetables, cultivate flowers and manage agricultural fields. Agricultural Internet of Things is a revolution in science and technology. First, the use of agricultural IoT technology can make the item identifiable, traceable and inheritable. According to the soil properties of crop growth, adjust the crop inputs, identify the soil properties within the plots, to achieve precise control, but also to determine the production goals of crops, to locate the "system diagnosis, optimization formula, technology assembly, scientific management" Or most saved investment to achieve the same income or higher income. Second, agricultural Internet of Things technology has established a set of modern agricultural operation technology and management system. With information technology support, we can get real-time information on irrigation, soil air changes, environmental conditions of livestock and poultry, as well as large-scale surface data testing to collect temperature, humidity, wind, atmosphere, rainfall and land humidity, nitrogen concentration, Soil pH value and other aspects of the data, so as to achieve scientific monitoring and scientific planting, to help farmers disaster, disaster reduction and improve the overall efficiency of agriculture to provide scientific basis for agricultural management decision-making and promote the transformation and upgrading of modern wisdom agriculture. Third, agricultural Internet of Things technology has promoted the development of agricultural informatization. The development of IoT needs the establishment of information superhighway, the rapid development of mobile Internet and the popularization of broadband network are the basis for the massive information transmission and interaction of IoT and the precondition for the vigorous development of IoT. According to industry estimates, China's Internet of Things industry chain in the future each year to create 100 billion yuan output value and showed a year-on-year growth trend, the application of Internet of things technology has become the post-3G era and 4G era's largest market excitement. The development of a smart agricultural Internet of Things is an important move put forward by the Chinese agricultural sector. The rapid development of the agricultural Internet of Things in recent years has brought about new modes of agricultural production and management, improved the efficiency of agricultural production and promoted the transformation and upgrading of modern agriculture. Under the new situation, the main body of agricultural production and management at all levels should rely on technological innovation to promote the integration of information and modernization of agriculture and the development of the Internet of things, and to support smart agriculture so that this smart new type of agricultural project can better serve the peasants.
