Data Logging Technology
A data logger is a basic box capable of picking up and storing signals from sensors.
For ease of use they generally have a minimum number of displays and controls and their portability enables remote data logging for example logging data away from the computer.
Data loggers are either fitted with an internal battery that is rechargeable or use regular alkaline batteries.
Some may also have external power supplies. Most data loggers store data in non-volatile memory, which means the data will not be lost if the power supply fails.
