The Wireless Light Sensor provides live data for light level (lux), illuminance, UV Index, and color intensity.
See the Buying Guide for this item's required, recommended, and additional accessories.
The Wireless Light Sensor features two separate apertures - one for ambient light measurements and one for directional light measurements. The ambient sensor measures illuminance and UV Index, while the spot (directional) aperture measures light level and color intensity. Our software displays the relative intensities of Red, Green, and Blue light, then sums them to determine the level of White light. PAR and irradiance are also available as calculated measurements within PASCO Capstone (version 1.8 or later) and SPARKvue software (version 2.6 or later).

Visit PASCO's Experiment Library to view all activities for this product.
In this lab, students use a light sensor to compare how organisms, including humans, are able to see. Then, they will compare the light sensitivity of organisms to what an electronic light sensor can detect.
In this lab, students will use light and absolute pressure sensors to measure changes in light and pressure in an aquatic ecosystem as an Elodea or other aquatic plant undergoes photosynthesis.
Students measure the intensity of a light source vs distance. Using their data they explore the mathematical relationship between intensity and distance and discover the inverse square relationship.
In this lab, students use a light sensor to measure the light level that falls on a simulated earth's surface as it turns through several rotations.
In this lab, students will use light sensors to study the effects of polarization on light intensity and to explore Malus’ Law.
In this lab, students will use light sensors to explore how light intensity varies inversely as the square of the distance from a point source of light.
