  • ・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.
