Texas Instruments OPT3006 Ultra Thin Ambient Light Sensor

Texas Instruments OPT3006 Ultra Thin Ambient Light Sensor is a single-chip lux meter measuring the intensity of visible light as seen by the human eye. The OPT3006 is available in an ultra-small PicoStar package, which fits into tiny spaces. The precision spectral response of the sensor tightly matches the photopic response of the human eye. With strong infrared (IR) rejection, the OPT3006 accurately meters 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 design requires mounting the sensor under dark glass. The Texas Instruments OPT3006, often in conjunction with backlight ICs or lighting control systems, creates light-based experiences for humans and is an ideal replacement for photodiodes, photoresistors, or lower-performing ambient light sensors.
