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.
