Data Logger, which is also known as a Data Recorder, is an electrical device that performs the task of recording data over a time period. It can even record data from sensors or instruments which are externally located. Data logger consists of inbuilt sensors that have the capacity to read data from external sensors. It works on microprocessor and battery charger, the size of this device is small. You can attach this device with a computer and retrieve data. The device can also act as a standalone instrument, as it can work with its own keyboard and display screen.
Data logger basically captures as well as stores data, this device has got data capturing elements like plug-in-board. It also has a special inbuilt device which is the data acquisition device that is like a serial communication system which works from the main computer. It is the main computer which performs the function of data recording system in real time.
Now let us check out some of the basic functions of data loggers. They have a multi functional ability. Let it be any sort of electrical signals, it has got the capacity to read all of these signals in a very minimum time frame.
Once the data recorder reads all types of electrical signal, it stores them straight in the internal memory. And once the internal memory captures this data, you can easily download this information straight to your computer. But this does not mean that loggers always need the help of a computer, as it can work without a computer too.
Nowadays people use data recorders for a variety of reasons. Now let us take a sneak peek at some of the basic applications of data recorders. They are used in the weather station in order to record data like wind speed, temperature, solar radiation etc. It is also used in test equipments to record hydrographic data like collecting information related to water depth or level.
The logger is also used to record data like moisture level of soil, gas pressure, tank level, road traffic, vehicle test, monitoring environmental issues, application for troubleshooting, railway signal, calibration service, management of energy consumption, research in wildlife and many more.
In many industries where the basic function is to store food items, you will find a massive use of multi channel temperature data logger. Here the device not only reads the temperature but it has humidity sensor which reads the humidity and makes sure that goods are in their perfect condition. Even in many restaurants also people use this device in the refrigerator in order to detect the temperature. It provides information of the temperature and makes sure that the food is in its best condition.
Data loggers come in both small as well as large sizes. Moreover, you will find this device in various price ranges, so depending upon your usage and budget you can choose your data logger. If you are looking for cheap data loggers then you can opt for the single channel loggers, but if budget is not a constraint for you then you can opt for the multitude data loggers.
