Product Summary
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 filtered light to a calculated total value of the 3 lights. Our white light sensor is just the unfiltered response from the chip of an unfiltered portion of the detector. The light available to drive photosynthesis (PAR), total light power per area (irradiance), and relative brightness to the human eye (illuminance) are also available as calculated measurements within PASCO Capstone (version 1.8 or later) and SPARKvue software (version 2.6 or later).
Features
- Wirelessly connects to computers, Chromebooks, tablets, and smartphones
- Simply pair and go, no cables or adapters to manage
- Onboard 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
Applications
- 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
