Data Logger

A data logger (also datalogger or Data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered and portable.

Basically three types of instruments are commonly used for collecting and storing data. They are

1) Real-Time Data Acquisition Systems

2) Chart Recorders and

3)Dataloggers

datalogger for school are normally more economical than chart recorders. They offer more flexibility and are available with a greater variety of input types. Most data loggers collect data which may be directly transferred to a computer. Although this option is available with some recorders, it normally adds significant expense to the recorder price.

Data acquisition systems offer a great deal of flexibility and are certainly attractive when high sample rates are required, however, since they require connection or installation into a computer, the computer must also be present and active when collecting the data. Data loggers can collect data independently of a computer. Data is normally collected in non-volatile memory for later download to a computer. The computer does not need to be present during the data collection process. This makes them ideally suited for applications requiring portability.

hello dyy2008

Was curious to find out just why you posted a string on data loggers and remote access recording devices whilst very interesting, i doubt if anybody on the forum would have much use for them other than people like myself who use them for work. They tend to be both expensive and specifically designed to log data from highly specialised sensory arrays like Geophones or geodetic survey equipment like the Lica remote user GPS total surveying station that i use at work which would although useful for some specific Astrophysical measurements would be way outside most people budgets on this forum coming with the price tag of nearly £12,000.just for the total station you then have the added cost of the drongle and more importantly the special computer software needed to record the data sets which cost and additional £1000

and so for these reasons please excuse the curiosity for the post best wishes and dark skies Pete
