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 temperature data logger 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.
