The Role of Precision Agriculture in Smart Home

Precision agriculture based on the Internet of Things technology is a new trend in the development of agriculture in the world today. The traditional agricultural model is far from adapting to the needs of sustainable agricultural development. Problems such as product quality, severe shortage of resources and widespread waste, environmental pollution, and diversification of product types have caused the development of agriculture to enter a vicious cycle, while precision agriculture uses hi-tech. The exchange of technology and science management in exchange for the greatest savings of resources has provided a bright road for the development of modern agriculture. It is a system based on spatial variability, positioning, timing and quantitative implementation of a set of modern agricultural operating techniques and management supported by information technology. Its basic working principle is to adjust the input to crops based on the soil properties of crop growth. Identify the spatial variability of soil properties and productivity within the field, and determine the production targets of the crops, and conduct positioning “systematic diagnosis, optimization of formulas, technology assembly, and scientific management” to increase productivity and achieve the lowest or most economical investment. The same income or higher income, and improve the environment, efficient use of various types of agricultural resources, access to economic and environmental benefits.

The role of wireless sensor network in precision agriculture

For the realization of precision agriculture, the key technology is the application of wireless sensor network. It will connect sensors in a specific area to form a network through wireless communication, forming an infrastructure for a sophisticated agricultural management information system. Changes in the environment, object location, observation of specific parameters, etc., and then make the appropriate operations, data transmission and other ancillary operations to achieve wireless, real-time transmission of farmland information. At the same time, it can provide users with more decision-making information and technical support. Users can search through terminals such as computers and mobile phones anytime, anywhere, and realize remote management of the entire system.

Precision agricultural automation system based on wireless sensor network transforms precision agriculture from conceptualization to industrialization. Wireless networks have high transmission bandwidth, strong anti-interference ability, good security and confidentiality, and low power spectral density, mainly through temperature sensors and soil. Sensors, humidity sensors and temperature controllers, moisture controllers, air testers, and automatic sprinkler systems are connected to communicate with the remote antenna matrix through the WI-FI device server. The temperature, humidity, and soil dryness are then transmitted through the light-borne wireless switch. The data is sent to the remote intelligent system in real time, and the data is sent to agricultural personnel and agricultural experts through the mobile phone or handheld terminal, which provides data basis for remote guidance and decision-making of agricultural experts.

Video image and sensor data collection: Through the camera and terminal sensors, data on the real-time pictures of the facility's agricultural field, crop growth greenhouses, outdoor air temperature, humidity, and soil temperature and humidity data are collected. Acquisition method: The video screen is continuously collected, and the sensor data is automatically collected periodically. The collection period can be set according to the user's requirements, or the user can modify the cycle time through the terminal temporarily.

The replacement of traditional agriculture by intelligent precision agriculture is an inevitable trend of agricultural development, and it is more in line with China’s national conditions. Smart and fine agriculture can promote the transformation of agricultural development methods, achieve the sustainable development goals of efficient use of various types of agricultural resources and improve the environment, and can not only maximize agricultural productivity, but also achieve high quality, high output, and low consumption. Environment-friendly sustainable development of agriculture is an effective way.
