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).
- Wirelessly connects to computers, Chromebooks, tablets, and smartphones
- Simply pair and go, no cables or adapters to manage
- On-board memory enables the sensor to function as an independent datalogger
- Variable sampling rate for short, precise experiments or lengthy, multi-day data collection.
- Bluetooth connectivity and long-lasting coin cell battery
- Indirect PAR measurements for biological studies
- Studying solar energy
- Monitoring UV light levels
- Reflection, absorption, and transmission of light through clear, opaque, and variously colored translucent mediums.
- Investigating polarization and reflectivity
- Modeling planetary motion
- Verifying the inverse square law
- Investigating insolation (solar radiation) and seasons

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 a light sensor to measure the amplitude and frequency of vibrations during three simulated earthquakes.
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 and absolute pressure sensors to measure changes in light and pressure in an aquatic ecosystem as an Elodea or other aquatic plant undergoes photosynthesis.
In this lab, students will use a light sensor to investigate the relationship between the earth's tilt on its axis, its revolution around the sun, and the seasons.
In this lab, students will use light sensors to investigate how light intensity changes as it gets further from the source.
