Intelligent greenhouses, smart agriculture, smart homes, smart cities, and intelligent transportation are the specific applications of IoT technologies in various fields. The technical foundation of German Industry 4.0 is also Internet of Things technology. At present, all walks of life are struggling to take a ride on the Internet of Things and take advantage of the situation. Smart agriculture is a typical example of the development of agricultural internet of things.

Compared with large-scale planting abroad, the modern agricultural technology in the United States and Israel is quite mature. China's agricultural cultivation is relatively backward and is currently undergoing a transformation from traditional individual planting operations to large-scale modern planting agricultural operations.

For the application of IoT technology in agriculture, the basic technology is a sensor network. The improvement of the sensor network system directly affects the operation of the entire agricultural IoT technology. The collection of data on the production site, the transmission of data, the processing and control of data information are the deeper core technologies of the Agricultural Internet of Things. The use of sensors to collect information on air, soil, pests and diseases, agricultural operations and other production processes, and the information will be transmitted to the cloud platform, through the cloud platform for processing, providing data support for production management, quality tracking, agricultural technology services, etc. is the Internet of Things technology in agriculture The main application.

In the past two years, the Internet of Things technology has been applied to many fields of agriculture, including agricultural environmental monitoring, production control of greenhouses, water-saving irrigation, weather monitoring, product safety and traceability, and intelligent equipment diagnostic management.

In the traditional plant management with experience management as the main model, due to different experience in fertilization, spraying, irrigation, etc., different planters will have different planting results, causing waste of water resources, excessive fertilizer spraying, and so on. With the continuous promotion of large-scale planting and the continuous change of industry conditions, traditional experience management cannot adapt to the large-scale production operation mode, and scientific advanced management methods will surely replace it.

The application of the Internet of Things technology can capture greenhouse production environment information and keep abreast of animal and plant dynamics. Sensors will play an indispensable role in agricultural production. The fertilization, spraying, irrigation, etc., all require sensor data collection. Through the data on the soil, pests, and humidity of the planted products to determine when to fertilize, when to spray, when to irrigate, and the amount needed, Avoid waste of resources and damage to the environment in traditional empirical management.

When the air temperature, humidity, soil moisture, and CO2 concentration collected by the sensor approach or exceed the optimum growth value of the crop, the intelligent temperature and humidity monitoring system based on the Internet of Things technology prompts the grower by SMS, etc., and the grower can Remind timely action to ensure optimum crop growth environment.

Through the data transmitted by the sensors, the information of crops can be grasped at any time and at any place, crops can be remotely managed, and scientific diagnosis and analysis can be conducted through expert and expert systems on the relationship between diseases, pests, growth and environment of crops. By monitoring data combined with big data from time to time, giving crops suitable growth environment and nutrition, crops grow fast on one hand and grow well. At the same time, they are not easy to get sick, which can bring better economic benefits.

The front-end production data collected by sensors is not only used in the production area. In the later stage of product circulation, quality traceability also needs to rely on front-end production data support. Perfect front-end production data can provide important data for every link in the crop production process, and can provide a good guarantee for product quality.

The application of the agricultural internet of things can free the labor force from heavy physical labor. Instead of watering on site, it is not necessary to uncover or cover the insulation. The computer will make decisions based on the collected data through its own expert system.

At present, the Internet of Things technology has started in agriculture, and agricultural companies are beginning to realize that they must accept this reform. With the continuous increase in the cost of labor, the continuous reduction in hardware costs, and the growing trend of agricultural IOT, the future of agricultural IoT will completely change. Agricultural production methods and consumption methods. The development of agricultural IoT is a general trend. The future of agricultural IoT will completely change the mode of production and consumption of agricultural products. The advantages of agriculturalization in the future cannot be underestimated.
