A data logger is an electronic device that is used to store data over time. Data logging includes many data acquisition devices such as plug-in boards or serial communication systems which use a computer as a real time data recording system. Wireless transmitters are also capable of turning a regular smart phone (or tablet) into a mobile logger.
What can a data logger be used for?
Data loggers are used whenever there is an advantage to recording conditions over a period of time. Common data logging applications include wind speed, the temperature in refrigerated storage containers, and monitoring the flow rate of liquid at a pumping station. Traditionally, after the data acquisition period, the device would be retrieved and the data downloaded. However, data loggers can also transmit data wirelessly to a PC, saving the time and expense of manual collection of devices in remote areas, and providing higher quality data than is possible in a manual recording.
How to choose a data logger?
Most data loggers are general purpose devices although some are optimised for a specific type of sensor connection and reading (temperature being the most common). Data logging equipment may be selected for one particular task or as an addition to an inventory of data acquisition hardware.
