Light Sensor Measurement Concepts

Jared from FunScienceDemos introduces the concept of measuring various physical properties, including temperature, length, weight, and light. He explains how light is measured in Lux using a light sensor. The video demonstrates the use of a light sensor to measure the brightness of different light sources, comparing a bright light to a candle flame. The video concludes with a mention of Vernier, a company that provides educational sensors and software.
