The OPT3005 is a sensor
that measures the intensity of visible light. The spectral response of the sensor
tightly matches the photopic response of the human eye along with extreme rejection
to 850nm and 940nm infrared light over a wide angle of incidence.
The OPT3005 is a
single-chip lux meter, measuring the intensity of light as visible by the human eye.
The precision spectral response and extreme IR rejection of the device enables the
OPT3005 to accurately meter the intensity of light as seen by the
human eye regardless of light source and any stray light from 850nm or 940nm active
illumination. The extreme IR rejection also helps to maintain high accuracy when
industrial design calls for mounting the sensor under dark glass, especially with
active 850nm or 940nm NIR illumination. Such systems typically have a lot of NIR
stray reflections from the cover glass which can affect the light sensor
measurement. The precision optical filtering of OPT3005 is verified for
resilience to such stray NIR refection and truly measures the ambient light as
perceived by human eye. The OPT3005 is designed for systems that create
light-based experiences for humans, and is a preferred replacement for photodiodes,
photoresistors, or other ambient light sensors with less human eye matching and IR
rejection.
Measurements can be made from 20mlux
up to 166klux without manually selecting full-scale ranges by using the built-in,
full-scale setting feature. This capability allows light measurement over a 23-bit
effective dynamic range.
