Handheld Data Logger

A data logger is an electronic device that records data over time either with a built in instrument or sensor or via external instruments and sensors. They are based on a digital processor and generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Data logger that we developed was a stand alone type with and LCD interface. This device was designed to be used by students so that they can record their experiment data and later use that in their reports.
