Understanding The Basics Of A Data Logger
When the meteorologist reads the local forecast, it is because
of his/her accurate assessment of the data logging factors. In
addition, water levels, depths and flow can be measured this
way. If you have ever read the newspaper and see a listing for
how many people traveled on a certain highway over the weekend,
perhaps you wonder how that assessment was made. Did someone
stand outside and count each individual car or truck that passed
by? Well, no, but a computer did. Road traffic counting is
another example of data logging.
A data logger is defined as an electronic computerized device
that records data over a predetermined amount of time. Depending
on the job, some data loggers are small while larger machines
are used for more extensive research. These units acquire data
according to the programming and store it into memory or a
storage unit. This memory can be set to accommodate days, weeks
or even months without ever having human intervention. Modern
data loggers use a battery to promote storage in the units
memory Older models use paper or disks, but technology has all
but rendered these earlier models extinct.
Data loggers are so accurate that, in addition to recording
detailed information, they often provide a time and date
indicator to ensure that all of the recorded data can be broken
down and associated with a specific date and time for
informational research purposes. This is possible because of
their built in clocks, which easily provide an accurate reading.
>From the simplest of device to a complex unit, data loggers
offer a wide range of flexibility for nearly any data retrieval
job. The more simple devices are, as expected, easier to
program. The more complex the unit, the more work that is
involved. Some of the most modern data loggers offer website
capabilities, which allow individuals to surf onto a website and
monitor the tracking system. This works well for users who enjoy
real time information, including weather data, web cams, etc.
During harsh weather conditions, troublesome water levels or
other concerns, a data logger can be linked to devices,
including modems, cell phones or satellites. This capability can
keep individuals updated on the status of weather conditions,
but also alert them if immediate attention is required. If you
ever notice a weather warning interrupt a radio station or
television broadcast, that information is coming from a data
logger that is responsible for monitoring weather conditions.
The information is then relayed to the meteorologist, who gets
the information out to the public.
As individuals, it is difficult to realize the complex nature of
data loggers and their responsibilities. But, without them, we
would certainly become aware of their absence. Without a way to
measure such important data factors, without an efficient way to
report them and research certain data, we would be forever
uninformed.
