Agricultural Internet of Things, that is, the Internet of Things that participates in automatic control through real-time display of various instruments or as parameters of automatic control. It can provide a scientific basis for the precise regulation of greenhouses, and achieve the purpose of increasing production, improving quality, regulating growth cycle and improving economic benefits.

Agricultural Internet of Things is the application of Internet of Things technology in agricultural production, operation, management and services. Network and Internet transmission, integrate and process the obtained massive agricultural information, and finally realize the process monitoring, scientific decision-making and real-time service of agricultural pre-production, production and post-pro···

Sensor technology is a high-level product of the development of modern agriculture, and it is also the technical core of smart agriculture. Under the macro-control of the Internet of Things, sensors can sense the environmental needs of different crops according to the current planting characteristics of agricultural products. By implementing intelligent monitoring on them, planting efficiency and ···

Smart agriculture is the deep integration of the Internet of Things and traditional agriculture. Sensors can not only solve the limitations of natural factors such as temperature, but also complete remote control scientific research and detection in fields, greenhouses, aquatic products, livestock and other industries, and reasonably reduce the consumption of human resources.

big data can be said to be a technology trend that complements and multiplies with the Internet of Things. In agriculture, the Internet of Things plays a role in precise control and greatly improving production efficiency, making agriculture, fishery and animal husbandry reach an unprecedented level of refinement. On the other hand, the biggest role of big data in agriculture, fishery and animal h···

Among them, sensors (temperature sensor, humidity sensor, PH value sensor, illuminance sensor, CO2 sensor) are the key components of the agricultural Internet of Things.

The Internet of Things is based on the computer Internet, using RFID, wireless data communication and other technologies to construct an "Internet of Things" covering everything in the world. In this network, items (commodities) are able to "communicate" with each other without human intervention. Its essence is to use radio frequency automatic identification (RFID) technology to realize the autom···

Five key technologies of the Internet of Things The foundation of the future Internet of Things industry Long-range wireless network communication technology

The cellular-based Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth, and can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades.

NB-IoT user terminals can work in power saving mode to reduce power consumption and prolong battery life. When the user terminal works in the power saving mode, similar to the shutdown of the device, it seems to be disconnected from the network, but the user terminal is still registered in the network and does not need to re-attach or re-establish a packet data network (Packet Data Network) connec···
