Witty Fox - OPT3001 Digital Ambient Light Sensor OPT3001 Digital Ambient Light Sensor is a single-chip lux meter that measures the intensity of light as visible by the human eye. Measurements can be made from 0.01 lux up to 83k 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. The OPT3001 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. The precision spectral response and strong IR rejection of the device enable the OPT3001 Light Sensor to accurately meter the intensity of light as seen by the human eye regardless of the light source. The strong IR rejection also aids in maintaining high accuracy when the industrial design calls for mounting the sensor under dark glass for aesthetics. The OPT3001 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.
