Data logging is the process of gathering information to understand a system or process. Loggers store information such as temperature using sensors and can be standalone or PC-based. Data logging is used in various situations, including weather systems and aircraft black boxes. It provides vital information for performance, quality, efficiency, and cost reduction. The equipment has evolved from bulky mechanical recorders to sophisticated computers and microprocessors. Data logging devices are used in everyday life, from credit card transactions to weather reports.
Data logging or data capture is, in its simplest terms, gathering information to learn more about a process or system. It forms the basis for understanding a wide range of systems.
Logging and saving information provides greater knowledge and sometimes better management of how and why different processes work. Many loggers store information such as temperature using sensors and then convert the information into electrical signals. The data is archived and once retrieved it can be filtered and understood correctly.
To start the process we need a data logger. This could be a standalone logger or a personal computer (PC) based device. The datalogger is a tool that connects to other devices for the sole purpose of collecting information.
The standalone logger has many advantages over the PC-based logger. Many have their own backup power source in the event of a power outage so that vital information is not lost in the event of a power outage.
Because the stand-alone is designed specifically for data logging, it can process data faster and more efficiently and can have many more sensors than a PC. The information from the standalone logger can then be transferred to a personal computer.
Data logging is used in a variety of situations. A simple example is the black box recorder in an aircraft, which collects information about the aircraft’s flight for later use. Another is a weather system logger used by meteorologists to detect temperature and pressure in order to determine upcoming weather conditions.
Data logging involves collecting statistics which are used to give you a better understanding of the field you are working in. Information is needed in all types of business to determine performance, quality, efficiency cost reduction, fuel consumption and many other vital information uses.
There has been an evolution in data logging and the type of loggers used over the years. In the past, the equipment was bulky and mechanical, using huge paper recorders. Now, sophisticated computers and microprocessors retrieve information in much more detail than could have been processed before.
Loggers are used in everyday life unknowingly by the public.
The next time you are in a supermarket and hand over your credit card or store card, a data logging device can track your spending movements from the store. It can evaluate what items you’ve bought, how many times a month you buy them, and even how often you use the store.
In today’s society almost all information from the weather to our purchasing habits ends up in a data logger. The information is archived and saved for later use.
