Assalammualaikum
and hello everyone..
Next, I would like to show what is the meaning of
data logger. I hope this post will give benefit to you all. Let's enjoy
reading.
Data
logger is one of the technology that been used in conducting the science experiments
in the school. It is used to store the data which includes many data acquistion
devices such as plug in boards or serial communication systems that use a
computer as a real time data recording system. The data that been stored could
be pressure, current, temperature, light intensity, soil moisture and
resistance. It is compact, battery powered devices equipped with an internal
microprocessor, data storage and sensors. There are three different type of
data logger which are stand- alone data logger, web- based data logger and wireless
data logger.
The
advantages using the data loggers is that they can operate independently of a
computer unlike many other types of data acquisition devices. If we using the
data longger, the chance of having an error is less. This is because the
measurement of the data is always taken at the right time. Other than that, when we used the data logger,
mistakes are not made in reading the results compare to the human that often make
an errors in this experiment. Example that we can see is sometimes we are easy
to misread the temperature using the scale on a thermometer. Therefore, if we
use data logger doing the experiment, we can ignore the error that occur when
taking the reading of the temperature. In addition, we also can produced graphs
and tables of the results of the experiment automatically by the data logging
software. This will save the time where we need to plot for ourself the graph
and table that we need in the experiment conducted.
