-The BH1745NUC is virtual colour sensor IC with I²C bus interface.
-This IC senses Red, Green and Blue mild (RGB) and converts them to digital values.
-The high sensitivity, wide dynamic range and extraordinary Ircut traits makes this IC the maximum appropriate to reap the illuminance and shade temperature of ambient mild for adjusting LCD backlight of TV, cell cellphone and tablet PC.
-It is feasible to come across very extensive variety light depth. (zero.1/2 – 40k lx)
Features
-The High Sensitivity and Wide Dynamic Range (0.005 – 40k lx)
-Supports Low Transmittance (Dark) Window
-Correspond to I²C Bus Interface
-Low Current by Power Down Function
-Rejecting 50Hz/60Hz Light Noise
-Correspond to 1.8V Logic Interface
-Programmable Interrupt Function
-It is possible to select 2 type of I²C bus slave address (ADDR =’L’: “0111000”, ADDR =’H’: “0111001”)
