Limited quantities are available. The replacement sensor is PS-3248.
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

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.
