Wireless Light and Color Sensor
(PS-3248)
Introduction
The Wireless Light and Color Sensor is a coin cell battery-
powered wireless sensor that connects to a computer or tablet
device through Bluetooth. The sensor measures light through
two apertures. The Spot Light Aperture measures red-green-
blue (RGB) and white light. The Ambient Light Aperture
measures illuminance (measured in lux, or lumens per square
meter), Photosynthetically Active Radiation (PAR) in sunlight,
and solar irradiance (in watts per square meter). The Ambient
Light Aperture can also be used to calculate the ultraviolet index
(UVI) of ambient light.
Either PASCO Capstone or SPARKvue is used to display and
analyze the measurements from the sensor. The sensor also
supports remote data logging for long term experiments; for
more information on this, see the PASCO Capstone or
SPARKvue online help. Since each sensor has a unique device
ID number, more than one can be connected to a computer or
tablet at the same time.
