Detecting movement in the visible light range, this light sensor emulates the human eye in spectral response. Choose from two different illumination ranges, which are easily selected on the unit’s setup menu. Chemistry, physical science, life science, and environmental science experiments involving light intensity, inverse-square law experiments, reflectivity, solar energy, and polarization are all possible to support with easy, accurate data. Includes Li-Ion rechargeable battery, wallcharger, quick reference guide, and a USB drive for collecting data. Range: 0–30,000 lx. Resolution: 0.5 lx. Sample Rate: max 1,000 samples/second.
