Electronic Sensors: Making the Connection
Johnson, Richard T.; Cotton, Samuel E.
Technology Teacher, v67 n8 p5-9 May-Jun 2008
For educational purposes it is not necessary to use expensive commercial-grade equipment to teach students about commonly used sensors. Schools frequently have limited funds for acquiring educational materials; therefore, purchasing sensors identical to those used in large-scale industry is not an option. By purchasing small-scale components that cost only a small fraction of what commercial systems may be using, schools can educate and engage students in a much broader range of authentic experiences. The focus of the activities presented in this article is directed at interfacing commonly available sensors with simple electronic components and inexpensive microcontrollers, which aligns well with STL Standard 11, "Apply the design process," STL Standard 12, "Use and maintain technological products and systems," and STL Standard 19, "Manufacturing technologies." The activities explore several cost-effective techniques for the study of selected sensors by interfacing them with very basic electronic circuits and easy-to-program microcontrollers. Presented here are ideas for implementing a course of study with several basic but interesting operational sensor systems together with some possible alternatives or enhancements.
