Data Logger
A data logger is an electronic device that records data over time or in relation to location either with a built in instrument sensor or via external instruments and sensors. This is the instrument where I was introduced to in my ICT class. After doing an experiment by using data logger, I have discovered that it has many advantages compared to the manual method. One of them is the experiment can be start or repeated at any time. Besides that, it also can use more than one sensor during the experiment. It is not limited to only one sensor at a time. For example, we can use temperature and humidity sensor together during our experiment of transpiration. We also observed that the temperature was measured accurately because it read until 0.001°C and this same goes to humidity reading. Moreover, if we do a manual experiment, we have to measure the time taken by using stopwatch right? But with data logger, it can measure time with 0.1s. We can see how accurate the data is. The other advantage is the data recorded in the data logger can be directly transferred into the computer to be analyzed.
However, data logger also has some disadvantages. We know that it is quite expensive, thus if it break down, there will be a problem to us to repair it because for sure the repair cost might also high. Data logger can be charged instead of using it direct from the plug, but it might out of battery power if we use it for a few hours.
Anything might have the advantage and disadvantages. But, a data logger has many benefits to us as a student. It helps us to run the experiment and get the data accurately. So, I suggest that this data logger must be used by the students in school. The experiment will be done in short time and the errors are not too much compared to manual method. The students also will be interested in doing the experiment such for a short time rather than waiting for some minutes or maybe hours to get the result.
