DATA LOGGER

Reflection Data logger

Last lesson, i had learned creating a blog, now my blog under progress. After that, i had introduced the alternative way to collect the experiment data which is by using data logger. Each group get a data logger, then i learned how to use it. The usage of data logger, it can detect many sensor in one time because the input of data logger are more then 1. The sensor must be placed and arrange from right side, it cant detect the input if placed it wrongly. By using the data logger, user can collect a data every second and the relationship of experiment variable could be see from the plotted graph from it. Data logger are friendly user because it easily to carry, make from unfragile materials and can stored data. By practising the data logger, we had did two experiment, first temperature and humidity, and second relationship of temperature and pressure. For the first experiment it done smoothly, but for the group experiment which is second experiment, some problem occur which is the pressure sensor. That sensor cannot detect the pressure reading of gas, so we repeat the experiment four time, the reading still same. So for the next day, we used other pressure sensor (PASCO), then we get the increasing reading of pressure and the relationship of pressure and temperature. From this simple situation, even the technology had build the easier way for human, but human did not appreciate the gadget well, I say that because, the pressure sensor was not service for a long time. Even though, our experiment got problem but it done in a short time, because we didn’t have to plot the graph and collect the data manually, because data logger had came out the data for each variables and graph for each variable in one graph. Everything have pro and contra, we should appreciate it and use it in good manners.
