~Reflection on Data Logger

Today, we learn about Data Logger. This is new thing for me because this is my first time know about data logger. I’m really excited to learn about it.

As a task, Dr Sadiah asked us to carry out an experiment using data logger. My group carried out experiment about Biochemical Oxygen Demand (B.O.D). We use sensor D.O to measure values of dissolved oxygen. To calculate B.O.D value, we need to calculate the value of final D.O minus the value of initial D.O. The highest value of B.O.D shows that the highest polluted water.

Then, we need to present our work to Dr Sadiah. Dr Sadiah gives her comment and advises to improve our work.
