Nowadays, students are losing their interest in science subject. This is because they do not able to apply theory on the science experiment while they are still using old and conventional method to conduct a science experiment that might bring a lot of uncertainties in the actual word. The current available data acquisition systems in the market are costly installation fee and stiff learning curve that leads to the inconvenience to conduct an experiment or analyze the result would be unwanted by the students. The objective of this project here is to implement a data acquisition system, which is user-friendly and low cost. Through this project, a data acquisition system is designed. Waterproof temperature sensor, velocity detector, voltage/current detector are used to carry out certain science experiments. With the standalone monitoring system, users can view the result and analyze on the liquid crystal display. The users also can read the result on a give website address as long as the Arduino Mega is connected to a computer. The use of Arduino Mega with Ethernet shield coupled together will help in accomplished the web site for the database in this project. Here the user has to enter a password, which must register before, and this read from the system for clarification and verification purpose. By storing the database online, the user can read his result in a more efficient way. This project has been extensively tested in one of the science experiments. Experimental results have shown a result accuracy of 90% in this project by compared to conventional method. From this project, a better way to conduct science experiment is built and this work would illustrate the advantages of saving the time for better experiment results while doing the experiment.
