Features:
・I²C bus Interface ( f / s Mode Support, Slave address "0101001". )・There are two outputs that peaks of a spectrum response are in visible light (Type0) and in infrared light (Type1).
・Illuminance to Digital Converter
・Very wide range and High resolution. ( 0.008 - 65535 lx )
・Low Current by power down function
・50Hz / 60Hz light noise reject-function
・Correspond to 1.8V logic input interface
・Light source dependency is little by calculating with Type0 and Type1.
( ex. Incandescent Lamp. Fluorescent Lamp. Halogen Lamp. White LED. Sun Light )
・Interrupt function is available.
・Adjustable measurement result for influence of optical window.
(It is possible to detect min. 0.001 lx, max. 100000 lx by using this function.)
・Small measurement variation (+/- 15%)
・Built in power on reset circuit.
