In the past decade, as the price of the sensor has dropped, the volume has become smaller and the performance has been more superior, which makes sensor technology widely used in more fields. In Jiangsu Province, modern farming technology in the Internet of things, the sensor can be seen everywhere.
Application Case of Domestic Aquatic Internet of Things and Its Sensor Technology Application
Internet of Things intelligent fisheries breeding
At present, the domestic aquatic Internet of Things is facing great market development. In the core area of ​​Tongli, Wujiang National Modern Agricultural Demonstration Zone in Suzhou City, the Internet of Things technology was applied to all aspects of management of the 320-mu pond intelligent ecological breeding base to realize the maximization of management intelligence and benefits. Through the new IoT farming methods, the effective realization of the experience of farming into data-based farming. The original 20 to 30 people, now only 5 individuals, greatly reducing labor costs.
In this new breeding mode, the Internet of Things has been vigorously applied. Installed in the fish tank edge of the sensor, can automatically monitor the water temperature, PH value, dissolved oxygen, COD and other seven indicators, push water, regular quantitative feeding, filtration, adsorption waste also adopts automatic operation.
According to reports, the Internet of Things includes the four systems of sensing, transmission, control and platform. The core is sensing the dissolved oxygen data of the water body collected by the sensor. This data relates to the success or failure of aquaculture, water oxygen, fish and crabs will die in batches. Breeding staff through the acquisition of updated data every 10 minutes, below the indicator will automatically turn on oxygen. Farmers can also remotely view the situation of fish ponds by using a smart phone and manually control the oxygenation by hand.
Next to the breeding base, is a 6,000-mu rice high yield demonstration side, rice fields into a square, a flat mirror. It is learned that in the process of crop cultivation, the growth of crops in the field is monitored by collecting data, using satellites, unmanned aerial vehicles, fixed sensors installed in the farmland, and hand-operated portable small sensors to collect crop growth information and farmland temperature in real time, Humidity and other environmental data. In a few years, while increasing production by 5%, it reduced blindly fertilization and improved the ecological environment.
