Motion Sensing Light Teaching Element

These slides, from the Technological Education Pathways Partnership (TEPP), lead students in a teardown activity to examine the components of a motion sensing light device. Wiring is exposed to add a manual toggle switch and then measure voltage and current. This setup can the be used to compare the performance of incandescent, CFL, and LED light bulbs. The activity includes a set of PowerPoint slide instructions as well as a PDF document on pyroelectric infrared radial sensors.
