The aim of this study was to develop a temperaturesensing USB I/O sensor platform system based on graphical monitoring and control techniques. Simple installation, built-in signal conditioning, and free supporting software make our USB I/O interface extremely easy-to-use. Additionally, this paper shed light on the contribution of applying the platform system for teaching students to understand the principles, functions, and applications of a temperature sensor and providing user experiences for them to acquire how to put it to use. Specifically, students used this platform to design a graphical program in advance to monitor the temperature sensor modules. The most important part of the proposed system is the implementation of the experimental USB I/O module in laboratory sessions.
