data logger experience

Hello my friend...one of the amazing technologies in ICT that we have learn is how to use 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. Increasingly, but not entirely, they are based on a digital processor. They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and utilize software to activate the data logger and view and analyze the collected data, while others have a local interface device and can be used as a stand-alone device.
We also already done experiment using data logger. The experiment was perspiration of hand using humidity and temperature sensor. It is an attractive alternative to either are corder or data acquisition system in many applications.When compared to a recorder, data loggers have the ability to accept a greater number of input channels, with better resolution and accuracy. Also, data loggers usually have some form ofon-board intelligence, which provides the user with diverse capabilities. For example, raw data can be analyzed to give flow rates, differential temperatures, and other interpreted data that otherwise would require manual analysis by the operator. As conclusion, data logger solve many problem that relate to experiment.
