The BH1745 is a 16 bit I2C digital color sensor IC that detects RGB (Red, Green, Blue) components and converts them into digital values. High sensitivity, wide detection range (0.005 to 40 k lx), and excellent IR cut characteristics make it easy to accurately obtain the color temperature and brightness of ambient light, making it ideal for backlight adjustment in TVs, tablets, PCs, and other LCD-equipped applications. The RGB Output allows calculation of Illuminance and Color temperature whereas High sensitivity and IR light filtering allows utilization of dark and tinted glass window without affecting uniformity of reading.
