Data Logger

Data Loggers are devices used to collect data on physical stimuli (temperature, humidity, etc), often over a period of time. This then is stored and can be accessed later. A data logger is usually connected to another instrument, such as a thermometer, and will record this instrument's data. This data will then undergo data preparation for appropriate information systems. It is a common input device which is a part of the infomation process known as collecting. Some good examples of items that can be attached to data loggers are weather balloons, thermometers, and anemometers.
