Low-Cost Retrofitted IoT Based Titration Setup for Remote Labs

Remote laboratories have become increasingly popular in the field of education as they allow users to conduct real scientific experiments from any location worldwide and at any time. However, most of the work in remote labs focuses on physics and engineering experiments. Remote labs on chemistry experiments are uncommon. This paper proposes a remote IoT-based setup for acid-base titration that makes use of an interactive web platform to control and observe the experiment in real-time. The setup requires no human intervention during experimentation as each step of the experiment is performed remotely by retrofitting the traditional setup. Data was gathered by having a selected group of students carry out the experiment multiple times. The paper performs an analysis of the accuracy of the experimental setup and presents user feedback on the experimental setup, the experience and its impact on their learning. The paper compares an alternate remote titration experiment with the proposed setup based on affordability using a comprehensive cost analysis.
