Measurements
The Spot sensor measures relative light levels in red,
green, blue, and white. The Ambient sensors measure
relative light levels in red, green, blue, white, UVA, and
UVB. Note that the software does not report red, green
blue, and white from the Aperture.
Measurements
* Based on solar radiance
*Sum of normalized RGB peaks
See Appendix B for more information about the
Measurements.
