cm3232e is an advanced ambient light sensor with i2c protocol interface and is designed by the cmos process. it is easy to operate via a simple i2c command.
  cm3232e incorporates a photodiode, amplifiers, and analog circuits in a single chip.  the best spectral sensitivity is used to closely capture real human eye responses. cm3232e hasexcellent temperature compensation and the robust refresh rate setting does not need an external rc low pass filter. software shutdown mode is provided, which reduces power consumption to be lessthan 1ua. cm3232e's operating voltage ranges from 2.5v to 3.6v. cm3232e can detect a wide range of ambient light power. under typical lens (transparency factor 10%),the maximum detecting lightstrength is over 40klux.
