A data logger is also referred as the data recorder it is an electronic technology base instrument or device that is mostly used to store the data maintaining the location relation with internally built sensors or through the external sensors and instruments .Many of the data logger devices are partially constructed on the computer processing methods. They are known as the immediate form of et data storage with hand held and portability features and extensively used in flight management data recording.
Data logger normally contains the little attached battery powered electronically and it ahs the microprocessor installed in it with internal memory for storing the certain amount of information. Also contains some internal sensor for the immediate activation of the device. Some of the data logger have interface software to transfer, view and analyze the stored data and other version use LCDs, keypad. The data loggers can also act as the stand alone device for determining the result of the collected information. Data logger s are available both in general and specific use. It spends on the purpose for what they re. Some of them are applicable in all types of scenarios and applications while other are typically designed to support the particular systems such as on airport data loge are used to record the immediate passenger data during the checking process. Common or general purpose data loggers are programmable and their parameters can be changed but specific purpose data loggers are non programmable and at as a static machine such as the chart recorders.
Some of the examples of the data logger instruments are the FDR equipment .flight Data recorders which are used to store immediate information. Another example could be CVR cockpit voice recorder that continuously records the voice and oral expression often pilot during the whole flight to analyze and prevent accidents or critical situations. Similarly Event Data recorders EDR are the tiny device installed by the manufacturers in the automobiles that is capable of collecting the data before and after the crash or accidents. Wide high band and voyage recorder in the ships to analyze the passage before passing also fall in the categories of Data loggers.
Cost And Advantages:
One of the major advantages of the data logger is that they are highly beneficial in providing 24 hour automatic updated information regarding any situation and time. Once activated they are automatically deployed for measuring a, string and analyzing the unattended values and conditions and secondly they are highly advantageous for getting most accurate picture of the envoi mental conditions and also for monitoring the disastrous affect in critical circumstances. In the early years of its invention it was deployed to the user at high price but with the passage of time the cost declined and now single channel of the data logger cost only $25 which is not a big price when its advantages are seen. Some of the advance and specific data logger may cost hundred of the dollar according to the internal specifications and configurations.
Data logger are experiencing rapid changes due to its rapid need and dynamic applicability in different work field such as weather stations, cold chains, Wildlife recording activities ,flight information systems, Rector systems, deformation, Environmental monitoring and profiling, water level monitoring etc. .The initial and most original versions of the data loggers can act as the stand alone devices as well as they can be effectively used for the wireless communications mostly in the alarming events and remoting activities. Their versatility makes future of the data logger bright. Currently they are also serving for the communication through FTP for transferring results daily in the user databases.
