Data Logger

A data logger 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. One of the primary benefits of using data loggers is the ability to automatically collect data on a 24-hour basis

A data logger is any device that can be used to store data. This includes many data acquisition devices such as plug-in boards or serial communication systems which use a computer as a real time data recording system.The advantage of data loggers is that they can operate independently of a computer. other than that we can repeat the experiment many times and its save time and energy. but it also have disadvantages because it is sensitive device  and it need handle with proper way.

this is the example set up of experiment using data logger
