Problem-based learning using a demonstration of sensor system

Developing students' thought processes is more important than memorization. Problem-based learning is one of the developments in this thought process. Problems in the field of science and engineering can be solved in a various solution. For example, using variety of sensor type devices which recognize various physical quantities such as sound, light, heat, force, etc., and process them with an embedded system. The result of processing can lead to something like record values to store as statistical data or control electrical equipment. This paper presents the design and construction of a demonstration kit of various sensors in embedded systems. To focus on using, students learn the working principle of various sensors and transducers. It can be used with simple embedded system. Finally, the problem is set, so that students can apply the knowledge for their solutions and present them as a group work.
