At present, Wisdom Agriculture promotes the most basic operation model in China. Simply put, it integrates various environmental data such as temperature, humidity and soil components through the sensing devices such as temperature and humidity sensors to access the database platform. The platform is compared to determine what data, conditions need to be adjusted, then activate the automatic control system, or open shed to add light, or automatic sprinkler, fertilization. So, constitute a circular planting system.

At present, in the field of control technology of agricultural internet of things in China, Internet of Things technology is mainly used for popularizing fine agriculture such as facility agriculture, aquaculture and animal husbandry, and is more suitable for use in agriculture with high added value such as planting flowers and medicinal plants and seedlings Cultivation and so on. And fields like rice and other crops, environmental factors, the cost of large investment, low output, Internet of Things technology is also difficult to apply.
Take Ningbo as an example. In recent years, a lot of facilities agriculture bases in the city have gradually introduced some Internet of Things technologies to enhance agricultural production efficiency with information control.

Fruits and vegetables in the city demonstration field of greenhouses, greenhouse temperature and humidity sensors, can be connected with the information collector. When the computer detects changes in environmental data, it will automatically prompt the start spray drip irrigation equipment, watering crops, fertilization. According to the director introduced to transform these intelligent greenhouses, before and after spending more than 130 million, three years down, the effect is good. In the past, it took 20 people and took 10 hours to water and fertilize it. Now it can be done in four or five hours with one or two people and a knife. As the director has counted, the intelligent facility can recover the costs in four to five years and in the long run, it is more cost-effective.

Sensor Monitoring System Equipment in Aquaculture
In the meantime, in Ningbo Wisdom Agricultural Extension, there are also some kinds of breeding owners who admit that large inputs do not necessarily have high output. It is not easy to make good use of things networking technology.
Huang is an aquaculture farm owner in Ningbo. Three years ago, he spent over one million yuan and introduced a set of intelligent aquaculture systems. Fish ponds placed on the water information integration equipment boxes, connected to monitor the water temperature, dissolved oxygen, pH and other sensors. Once the measured data has changed, Huang received alarm information on the phone, remote control of the aerator and other equipment through the network, timely disposal.

Pond aquaculture networking with sensors
Huang said that this system design is perfect, but has been disabled for more than a year. The fundamental reason is that the sensors and controllers can not stand the high temperature and humidity in the farm, and the harsh environment of strong seawater corrosion, always broken, the measured data is not accurate, combined with the subsequent high maintenance costs, and finally had to abandon.
It can be seen, at present, the domestic control technology in agricultural Internet of Things, the relative level of hardware manufacturing equipment is still relatively backward. The same sensor, imported parts can be used three or four years, more than double the life expectancy of domestic. In addition, like the soil test sensors, to really do a good job, the technical requirements are very high, the domestic rarely get shot, equipment bottlenecks need to be an early breakthrough. In addition, the high price and maintenance costs are also a hurdle for Internet-based agriculture.
Acrylic is the best new material for sanitary ware after ceramics.
Compared with traditional ceramic materials, besides the unparalleled high brightness, acrylic has the following advantages: good toughness, not easy to break; strong repairability, as long as the soft foam is dipped in toothpaste, the sanitary ware can be wiped new; soft texture, winter There is no icy feeling; the colors are bright, which can satisfy the individual pursuit of different tastes.
The use of acrylic to make basins, bathtubs, and toilets is not only exquisite in style, durable, but also environmentally friendly. Its radiation is almost the same as the radiation of the human body's own bones. Acrylic sanitary ware first appeared in the United States and has accounted for more than 70% of the entire international market.
