The OPT3004 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 and includes significant infrared rejection over a wide angle of incidence.
The OPT3004 is a single-chip lux meter, measuring the intensity of light as visible by the human eye. The precision spectral response and strong IR rejection of the device enables the OPT3004 to accurately meter the intensity of light as seen by the human eye regardless of light source. The strong IR rejection also helps to maintain high accuracy when industrial design calls for mounting the sensor under dark glass for aesthetics. The OPT3004 is designed for systems that create light-based experiences for humans, and is an ideal preferred replacement for photodiodes, photoresistors, or other ambient light sensors with less human eye matching and IR rejection.
Measurements can be made from 0.01 lux up to 83 k lux 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.
