What does a data logger do in electrical engineering?

A data logger is an essential tool used in electrical engineering that serves the primary function of recording electrical parameters over time for analysis. This device typically collects various types of data, such as voltage, current, temperature, and other relevant electrical metrics, at specified intervals. The recorded data can then be analyzed later to monitor performance trends, conduct maintenance, troubleshoot issues, or help in the design of new systems.

This continuous and automated collection of data allows engineers to identify patterns and anomalies that may not be visible during direct observation or manual measurements. Overall, the ability to gather and analyze data over time supports informed decision-making and enhances the reliability and efficiency of electrical systems.
