What is the difference between automatic weather station and handheld weather station?

Overview of Weather Stations

A weather station is a scientific facility used to observe and record atmospheric conditions. It collects a large amount of meteorological data through regular and continuous observation of various meteorological elements such as temperature, humidity, wind speed, wind direction, barometric pressure and precipitation. After being processed and analyzed, these data not only provide us with daily weather forecasts, but also provide important support for meteorological research, climate change monitoring, agricultural production, aviation and navigation safety, and other fields.

Automatic Weather Station

Automatic weather station is a kind of observation device that can automatically collect and transmit meteorological information. It can automatically detect several meteorological elements, such as wind speed, wind direction, rainfall, air temperature, air humidity, light intensity, soil temperature, soil humidity, evapotranspiration, atmospheric pressure, etc., without human intervention. These meteorological data are collected by meteorological sensors and processed by a microcomputer meteorological data collector, and then transmitted to the central station at regular intervals. The main components of the automatic weather station include meteorological sensors, microcomputerized meteorological data collector, power supply system, radiation-proof ventilated cover, all-weather protective box and meteorological observation bracket, communication module and so on.

Automatic weather stations have a wide range of applications, especially in fields requiring continuous and high-precision meteorological data, such as meteorological scientific research, agriculture, forestry, environmental protection, transportation and so on. They can be installed in fixed locations and transmit data through wired or wireless means to provide users with real-time and accurate meteorological information.
