Product Summary
Measure in bright sunlight to dim candlelight, and everything in between! Our Light Sensor has three ranges to accommodate a wide variety of student light measurements. Switch ranges with the touch of a button and without losing calibration. No other Light Sensor combines such a wide range with such high-sensitivity.
- Sensor communicates range changes to the computer, so readings are always correct.
- Mounts easily to PASCO apparatus.
Applications
- Compare light intensity vs. distance
- Study interference/diffraction/polarization
- Measure relative light intensities in daylight
- Compare relative intensity of reflected light from a variety of surfaces

Experiment Library
Perform the following experiments and more with the PASPORT Light Sensor.
Visit PASCO's Experiment Library to view more activities.
Polarization
In this lab, students will use light sensors to study the effects of polarization on light intensity and to explore Malus’ Law.
Inverse Square 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.
Light and Dark
In this lab, students use a light sensor to determine how light is related to what they see.
How a Greenhouse Works: Light
In this lab, students use a light sensor to determine how light or brightness depends on the angle at which the sun’s light strikes the surface of the ground and how this changes throughout the day.
Can Plants Survive without Light and Water?
In this lab, students use a light sensor to explore whether plants need light and water to survive and what adaptations help them survive.
Hunting with Light
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.
