An automatic weather station is a device that can automatically observe and store meteorological observation data. It is mainly composed of sensors, collectors, communication interfaces, and system power supplies. As the meteorological element value changes, the amount of electricity output from the sensing elements of each sensor changes. This kind of change is collected by the data collector controlled by the CPU in real time. After linearization and quantitative processing, the conversion from engineering quantity to factor quantity is realized, and then the data is filtered to obtain the values ​​of various meteorological elements. Hand-held weather stations are controlled by electronic equipment or computers, and automatically perform meteorological observation and data collection and transmission. Generally, they are composed of sensors, inverters, data processing devices, data transmission devices, and power supplies. Its use can improve the time and space density of conventional meteorological observations, improve the quality and reliability of observations, ensure the comparability of observations, reduce the cost of observation services, and improve operational observation conditions.

Hand-held meteorological station has advanced weather sensor technology. The accuracy and stability of the product are superior, and the meteorological element sensors are diversified. In addition to the basic 6-element sensors, sensors such as soil and water temperature, solar radiation, soil moisture, visibility, and clouds have matured products. Use flexible and changeable. The user can increase or decrease the type and quantity of sensors according to different requirements, and the actual operation is simple. Good protective measures. Automatic weather stations abroad are more perfect than domestic ones in terms of lightning protection, corrosion protection, etc., and are applicable to various complex environments. They also do a better job in the use of mobility, ease of operation, and quickness of maintenance.
Hand-held meteorological stations have been operating for many years in China, providing valuable meteorological data for meteorological observations, increasing the observation experience of meteorologists, and making great achievements for the meteorological observation undertaking in China. However, many problems have also been discovered. The structure of traditional automatic weather stations is centralized. The data collector must be matched with specific sensors, the system is not very open, and the compatibility among the collectors is not strong. It does not apply to the replacement of meteorological sensors or increase. Although the domestically-developed automatic weather stations are developing rapidly, production and investment operations are rapidly developing. However, due to the low level of technology, many hardware equipments rely on imports to meet, and there is still a certain gap from the world's advanced level. It can be seen that to further enhance the automation level of China's surface meteorological observations, it is necessary to retrofit and upgrade automatic weather stations, and to recognize the importance of automatic weather stations and the development status and prospects of automatic weather stations at home and abroad. The basis of automatic weather station reform.
