Reflection 3

In the ICT class, I'll also learned about data logger. What is data logger? Data logger is a device is 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. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and utilize software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device.



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. It is common for general purpose types to be programmable however many remain as static machines with only a limited number or no changeable parameters. Electronic dataloggers have replaced chart recorders in many applications...

One of the primary benefits of using data loggers is the ability to automatically collect data on a 24-hour basis. Upon activation, data loggers are typically deployed and left unattended to measure and record information for the duration of the monitoring period. This allows for a comprehensive, accurate picture of the environmental conditions being monitored, such as air temperature and relative humidity. Not only that, data logger also can used many sensor at the same time. It will recorded automatically across the adjust time. So, this device will make us easier to run an experiment and the result will be more accurate and precise. We also can save a lot of time as it can record the data automatically. Lastly, the data fro the data logger also can be convert into spreadsheet which we can make a graph easily with the recorded data...



As conclusion, the data logger will help the student and also teachers a lot in doing an experiment. This is one of the example that can teach a student to use technology and they also can learn in an attractive way using the devices...
