What is a data logger?

A device that stores data defined by the user or sensors is called a data logger. In order to learn how this device works and how to use it, we must first know what a data logger is and then learn about its use.
How data loggers work
Data loggers use sensors to convert stimuli and phenomena into electronic signals such as signals or voltages. These electronic signals are converted into binary data and then transferred to the computer or memory. Binary data transferred by computer or memory can be analyzed by software and stored on computer hard disk or storage media.
