Data Logger

what we understand about data logger???

do you heard about data logger???

now...we go step by step to understand what is DATA LOGGER...

Data logger an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. The reading the transferred into computer.

Our next assignment is application of data logger in sciences experiment at school. Our group was discuss about "global warming"...we use temperature sensor to detect the effect of temperature that causes of global warming. By using temperature sensor, we can see the changes  of temperature between 2 different air ( atmosphera and carbon dioxide) at the same time. The other advantage by using the data logger are :

•  Data loggers vary between general purpose types for a range of measurement applications to very specific devices for measuring in one environment or application type only
• Has an ability to automatically collect data on a 24-hour
• New innovative experiment possible
• Greater experience in practical work- the insulating properties of material
•   Better understanding on how it works.

But....data logger also have the disadvantage

-loss of conventional method of data collection

- The cost is quit expensive

- Reducing practice of graphing and drawing skill
