Sensors of all kinds play significant roles in the way that we use and interact with technological devices today. Smartphones, household appliances, automobiles, and other products that we use every day incorporate many different kinds of sensors. While the sensors are hidden from view in the products, appliances, and tools that we use, they nonetheless extend our senses in unique ways. Image sensors, accelerometers, gyros, temperature, motion, and proximity sensors and other types of sensors all work together to enable us to work smarter and enjoy a productive and healthful life. This article is just a start to integrate the currently available sensor technologies into a STEM project that can be used in the classroom. The introduction to different sensor technologies, particularly smart sensors, will encourage students to think about using off-the-shelf, readily available technical devices. Many different kinds of sensors can be added in a useful manner to projects such as the 3D Rover. The introduction and modification of the 3D Rover concept can be used in a variety of classroom activities and project designs. The 3D Rover can introduce students to a variety of sensor technologies that can be useful teaching tools in learning about our technological world.
