Compact Digital Color Sensor IC
The BH1745NUC I2C digital color sensor is designed to
detect the color components (RGB) in light and convert
them to 16bit digital values. Superior spectral sensitivity,
achieved through optimum infrared cutoff characteristics
and original optical technology, makes it possible to
calculate the color temperature and brightness with a high
degree of accuracy - even through dark tinted glass
windows - contributing to greater design freedom.
