Wireless Light and Colour Sensor

Brand: PASCO Scientific
 
Product Summary
The Wireless Light and Color Sensor features two separate apertures: One measures ambient light from the side of the box, and the other measures percent color of directional light at the end of the box.
 
Features
 
The ambient sensor measures:
Lux: light energy from a point in a direction (per steradian, a solid angle) per second
Illuminance: Light intensity per area, or brightness in our eyes’ perceivable range
Irradiance: Power of the light per area. (Depends on wavelength as UV light has more energy than infrared)
PAR (Photosynthetically Active Radiation): amount of light in the visible range 400 -700 nm available to stimulate plant growth
UV Index: 1 to 12 scale for the time light takes to cause skin damage. (Larger numbers cause burns faster.)
 
The directional spot sensor measures:
RGB: Light levels as a percent of the total of all colors measured
White: Total 'white' light intensity as a function of the sensor (on a scale of 65,536)
 
Applications
Studying solar energy
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
Indirect PAR measurements for biological studies
