Development of an Educational Demonstration Kit for Temperature Control Using an Analog PID Controller

Abstract

Temperature control systems are of paramount importance today, particularly in the industrial sector, where they are integral to maintaining product quality. However, the engineering education related to these systems often involves complex content and suffers from a lack of appropriate learning materials. This study addresses these challenges by developing an analog PID-based temperature control demonstration kit. This kit aims to enhance student learning in temperature control using an RTD Pt100 sensor for temperature measurement. It utilizes op-amp integrated circuits for processing and maintaining a constant temperature according to a set point. Furthermore, augmented reality (AR) technology has been integrated as an instructional medium to stimulate student interest and engagement. This approach emphasizes fostering a deeper understanding of the operational principles of temperature control systems. The target group for this study comprised 10 undergraduate students in Electrical Technology. The study's findings indicate that the developed demonstration kit is effective in promoting student skill achievement in PID control systems. All participating students scored above the evaluation criterion, exceeding 80%. Additionally, student satisfaction with the use of the demonstration kit was exceptionally high, with an overall average score of 4.61 and a standard deviation of 0.53.
