Data loggers benefit users in two ways. They avoid the time and expense of sending someone to take measurements in a remote location, and they enable much higher data density than is achievable through manual recording, providing higher quality data. Many different types of data loggers are available.

Information or data on your computer could be lost, if: The hard drive in your computer fails The data on your computer is corrupted for a variety of reasons Your computer is lost or stolen Your computer is in a fire or other environmental event A virus infects your computer and deletes or corrupts your files

Data loggers are electronic devices which automatically monitor and record environmental parameters over time, allowing conditions to be measured, documented, analysed and validated. The data logger contains a sensor to receive the information and a computer chip to store it.
