Connects directly to your devices via Bluetooth® Smart and covers a wide range of applications.
This is the most versatile and most cost-effective light sensor we’ve ever produced with a variety of measurements for the science classroom that is unmatched.
The Wireless Light Sensor features two separate apertures – one for ambient measurements and one for directional light measurements.
The ambient sensor measures illuminance, UVA, UVB, and UV Index. The spot aperture measures the light level and has color detection with channels for the relative intensity of Red, Green, Blue light and the ability to sum them for the level of White light.
Also, PAR and irradiance are available as calculated measurements in PASCO Capstone (version 1.8 or later) and SPARKvue (version 2.6 or later) software.
Note: The Wireless Light Sensor is not recommended for diffraction studies using our Optics Systems. For that, we recommend our PASPORT High Sensitivity Light Sensor or ScienceWorkshop Light Sensor.
Light measurements are key to the study of solar energy, modeling planetary motion, polarization, reflectivity, and the inverse square law.
- Studying solar energy
- Monitoring UV light levels and ways to limit exposure.
- Reflection, absorption, and transmission of light through clear, opaque and different colored translucent mediums.
- Investigating polarization and reflectivity
- Modeling planetary motion
- Verifying the inverse square law
- No interface needed! Connects directly to your computers, Chromebooks, tablets, and smartphones.
- Simplicity: just pair and go, no cables and adapters to manage
- Onboard memory allows the sensor to function as an independent datalogger.
- Variable sampling rate for capturing small fast changes or experiments that run for hours, days, or weeks.
- Features convenient Bluetooth wireless connectivity and long-lasting coin cell battery
Long term data collection directly on the sensor
In logging mode, wireless sensors collect data to their onboard memory for hours, days, weeks or even months at a time without needing to be connected to a computer, tablet, Chromebook or smartphone.
When the experiment is concluded, simply connect the sensor to a device running PASCO software and download all the measurements it recorded.
