AWS (Automated Weather Station)
AWS is an automated type of traditional weather station, either to enable measurements from remote areas or to save human labor. The system may report in several different ways. It may be in real-time via a local link to a computer system or via telecommunications or satellite systems. GSM mobile phone technology has also been known to be used. An alternative is the storing of the information in local data storage such as flash memory for retrieval at a later stage.
Most automatic weather stations have a Thermometer for measuring temperature, an Anemometer for measuring wind speed, a Hygrometer for measuring humidity, and a Barometer for measuring pressure. Some of them even have a rain gauge for measuring rainfall, Ceilometers for measuring cloud height, and a present weather sensor or visibility sensor.
