What Is a Data Logger?

A data logger is a computerized device that records information transmitted by other devices, storing it for download to a computer for analysis.

Independence

1. Data loggers operate independently of a computer, allowing them to be used in small spaces where it is impractical to connect a full computer.

Real-time and Logging

2. Some data loggers are able to transmit the data they receive in real-time to a host computer for analysis, while others simply record information for later retrieval.

Example of Use

3. An example of how a data logger may be used is to record temperatures in a particular environment, such as a truck, for the food transportation industry.

Speed

4. Data loggers can record information at a rate ranging from one sample per minute to 500 samples or more per second.

Programmable

5. Some data loggers can be programmed to record multiple channels of different types of input.
