In fact, the Internet of Things technology has been widely used in agriculture. The main application fields of the Internet of Things technology in agriculture can be divided into two categories: crop planting and animal breeding.greenhouse plantingNow greenhouse planting has widely used IoT technology for climate control, moisture monitoring, water and fertilizer integration, etc. in greenhouses. The more precise the environmental control inside the greenhouse, the better the crops will grow. At the same time, it has a great impact on crop growth, disease prevention and parasite production. последовательный модульGreenhouse Plant Networking Solutionclimate controlTo precisely control the climate environment in the greenhouse, it is necessary to consider the interaction between the control of light, temperature, air humidity and CO2 concentration, and also to control the influence of outdoor wind direction, wind speed, rain and light on the indoor environment. This involves the use of many sensors and actuators.Commonly used monitoring sensors include: air temperature and humidity sensors, light sensors, soil temperature and humidity sensors, atmospheric pressure sensors, and carbon dioxide sensors.Commonly used actuators include: sunshade motors, roll film motors, sprinkler control, drip irrigation, fans, roller blinds, heating, water valves, etc.agricultural weather stationThe automated agricultural weather station can monitor various data such as air temperature and humidity, light, rainfall, wind speed, wind direction, atmospheric pressure, PM2.5, noise, gas concentration, etc. in real time, and supports customized monitoring. By setting the relevant alarm thresholds, automatic alarms can be realized and the planting environment indicators can be precisely controlled.The moisture monitoring system is mainly aimed at monitoring the underground soil environment. The soil moisture monitoring system can realize long-term continuous monitoring of soil moisture. Users can flexibly arrange sensors to monitor soil moisture, soil temperature, soil conductivity, soil pH, groundwater level, and groundwater quality according to monitoring needs.Integrated water and fertilizer systemIn order to achieve the best growth status of crops, not only a suitable climate environment is required, but also enough nutrients must be taken in by the crops in a good water environment.The integrated water and fertilizer system allows water-soluble fertilizers to be added to irrigation water, and smart sensors can grasp the nutrient absorption of crops in time. The system parameters are flexible and adjustable, and the fertilization ratio can be changed so that the crops can take in the correct nutrients at the correct time. EC and PH control are suitable for greenhouse or field.poultry house monitoringThe breeding environment monitoring system can monitor the current air environment in real time through a variety of sensors, including air temperature and humidity, CO2 concentration, NH3 concentration and other environmental factors that have a greater impact on poultry growth.By setting the sensor data threshold, when the real-time monitoring environmental data exceeds the threshold, the on-site sound and light alarm can be sent or the alarm information can be pushed to the mobile client and computer management platform. The system can also draw each monitoring data into a curve for users to view and analyze historical data.In addition, high-definition cameras are used to monitor the poultry houses to detect existing problems in time and deal with them in time to avoid major losses.Livestock Internet of ThingsThe Internet of Things technology has penetrated all aspects of the livestock breeding industry to ensure the safety of meat from production to circulation.Electronic tags on livestockFeeding link: When the livestock is born and raised, RFID tags should be installed on the livestock, usually made into ear tags or ankle rings. Since then, the breeders have used RFID handheld readers to continuously set, collect or store information during the growth of livestock, and at the same time record the epidemic prevention records, disease information and key information of the breeding process of livestock in various periods to confirm that disease-free livestock can slaughter.Slaughter link: before slaughter, read the RFID tag information on the livestock with the RFID handheld to confirm that the livestock has a record of epidemic prevention and is healthy before they can be slaughtered and enter the market, and at the same time write this information into the packaging box label and cargo pallet label and price tag. ЗИГБИ-модульRegulatory links: In the process of market supervision, the regulatory authorities require all sales outlets to include RFID electronic tags in the cargo pallets, packing boxes and price tags, and write down relevant data such as the place of origin, product name, type, grade, and price of the meat. Enter the electronic label.Logistics distribution link: Fresh meat enters the circulation link, and RFID electronic tags are affixed to the pallets or boxes loaded with meat, and delivered to designated supermarkets or market sales points. When handing over the goods, it is only necessary to read the RFID electronic tags on the packing boxes or pallets through a fixed long-distance card reader or RFID handheld.
