BH1749NUC - ROHM

BH1749NUC Ambient Light Sensor

BH1749NUC is a digital color sensor IC with I2C bus interface. This IC senses Red, Green, Blue (RGB) and Infrared and converts them to digital values. The high sensitivity, wide dynamic range and excellent Ircut characteristics make it possible for this IC to obtain the accurate illuminance and color temperature of ambient light. It is ideal for adjusting LC.
