The development of precision agriculture is a core part of digital agriculture. As a new concept of digital, information and knowledge management of agricultural production systems, the practical application of precision agriculture will be of great significance in promoting the application of modern digital and information technologies to transform and upgrade traditional agricultural science and···

Agriculture is in the transition period from traditional agriculture to modern agriculture. To fully realize the transformation of this new technology system, network information technology will play a unique and important role and provide an unprecedented opportunity for the development of modern agriculture.

The demand for agro-meteorological sensors varies in many countries. The following are some of the countries that may have a high demand for agrometeorological sensors. China, India, USA, Brazil, Argentina, Mexico, Vietnam, Thailand, Australia, where agricultural production and irrigation is highly dependent on weather and climate and therefore the demand for agro-weather sensors is also high.

Some of the countries that will import more agricultural sensors and agro-meteorological sensors in 2020-2022 are：USA: The USA is one of the largest agricultural producers in the world and is the largest market for agro-weather sensors globally.Germany: Germany is one of the major agricultural countries in Europe and has a high demand for agricultural sensors and a relatively high import volume.

Market demand for agricultural sensors in Thailand and Indonesia and Malaysia and the Philippines：Thailand, Indonesia, Malaysia and the Philippines are all important agricultural producers in the South East Asia region with a relatively high demand for agricultural sensors and weather sensors.

How to choose and buy agricultural and meteorological sensors.In addition to agricultural and meteorological sensors, you can consider adding the following types of sensors.Soil moisture sensors: Used to measure the moisture content of the soil and can help farmers determine when irrigation is needed.Light sensors: These measure the intensity of light in the field and can be used to optimise crop ···

Soil moisture sensors can be used to monitor soil moisture and help farmers to rationally control the amount of water used for irrigation to improve crop yield and quality.Through the use of atmospheric temperature and humidity sensors, farmers can better manage the agricultural production environment and create a good growing environment, thus achieving high yield, quality and efficiency in agric···

Agricultural sensors are a very promising track. With population growth and climate change impacting on food supply, agricultural sensors can help improve food production efficiency, reduce waste and environmental pollution, and improve farmers' incomes and quality of life.

Sensors used in greenhouses include: temperature sensors, humidity sensors, light sensors, carbon dioxide sensors, soil moisture sensors and wind speed sensors. These sensors help the greenhouse manager to monitor the various parameters of the environment in the greenhouse so that timely action can be taken to regulate and optimise the growing conditions in the greenhouse.

Sensors are commonly used in outdoor agriculture: temperature sensors, humidity sensors, light sensors, wind speed sensors, rain sensors, soil EC sensors. These sensors help farmers and farm managers to monitor the environment in the public sector to improve the quality and yield of crops while reducing the cost and waste of resources in agricultural production.

Precision agriculture technology is an information-based agricultural management system that uses sensors as well as monitoring technologies to obtain necessary data about the land, make reasonable management measures based on the previous interactions of environmental factors affecting crop growth, and quantitatively control crop inputs and operations.

IOT technology combined with modern agricultural technology can realize the intelligent cultivation of agricultural products, better guarantee the quality and safety of agricultural products, easy and fast traceability of agricultural products and agricultural production information, etc.

IoT is mainly divided into 3 levels.The first level is sensor network, including RFID (radio frequency identification), barcode, sensors and other devices, whose role is to realize the sensing, identification, screening and collection of information.

In the process of crop growth, ecological environmental factors such as light, water, temperature, humidity, soil acidity and alkalinity, carbon dioxide, etc. play a comprehensive role, and any change in environmental factors may have an impact on crop growth, and there are differences in the requirements of environmental factors for different crop growth.

The specific application of IOT technology in agriculture has brought epoch-making changes in agriculture, people can understand the growth environment and growth situation of crops on the Internet, and agricultural IOT can realize the prediction, diagnosis and treatment of crop pests and diseases.
