Data Logging 101

Do you need a way to collect data, but don’t know how to get started? This overview will guide you through the basics of data loggers and how they can streamline data collection for your company.

What is a Data Logger?

Using a data logger you can keep an eye on just about any kind of data. But as with any type of electronics, there are lots of different manufacturers and models.

Data Logger vs DAQ

What is the difference between a Data Logger vs DAQ System? A data logger is a type of data acquisition system, but a data acquisition system is not necessarily a datalogger.
