Data Logger Basics

Introduction to Data Logging

For the non-technical, data logging is a generic term that describes the process by which an electronic device records information such as Temperature or Relative Humidity. So the words Data Logging mean much the same as recording.

Recording data has been around for hundreds of years but it has been a very labour intensive task because that information needed to be manually read or counted and then transcribed onto a written hard copy.

It is only in the modern era of the microprocessor that great strides have been made to make the collection of this information easier and more cost effective in the form of small portable electronic Data Loggers.

Data Loggers

An electronic data logger is a small self-contained miniature computer that once setup via a computer will operate independently of the computer using its internal battery. Data loggers are housed in a diverse range of cases that can allow them to operate in a wide range of conditions some of which can be quite extreme.

Software

Data Loggers are connected to a computer to be launched and can have their settings changed via software specifically designed for this purpose. Once the required data has been collected the same software will also be used to download the data from the logger and display that information on your computer screen. When this has been done an electronic copy of the data can be saved or printed out as a hard copy for your records.
