Abstract
This paper presents the experience of students' understanding in subject Instrumentation and Measurements. The approach of the study is to explore the real devices which is Passive Infrared or Pyroelectric Infrared to measure motion, by conducting a set of steps. Students need to do the calibration, design a system to capture motions and develop a real time monitoring using Graphical User Interface based on Python programming. This concept is different from the traditional method, which students just sit in the class and listen to the lecture. Through the experiment, the student team characterized the system's dynamic response and quantified random errors within a controlled environment. The result shows 93.72% of reliability and measured False Positive Rate of 153.09 triggers per hour. This finding leads to the students’ satisfaction which are 80% in understanding the Data Acquisition pipeline, 80% in understanding the effectiveness of real-time visualization and 70% in understanding the analysis of uncertainty and false trigger. This project provides evidence on the effectiveness in Instrumentation and Measurement education by implementing problem-based learning which can improve the students’ understanding in the foundational sensor physics in the modern IoT landscape.
