If you are interested in a new way to illustrate concepts such as the inverse square law for light and how light can be used for remote sensing of temperatures, read on. We have developed an inexpensive light meter using parts that are readily available from electronic supply stores. The light sensor responds not only to visible light but to near-infrared radiation as well so more of the electromagnetic spectrum can be investigated.
