DESCRIPTION

VEML3235 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.

VEML3235 incorporates a photodiode, amplifiers, and

analog circuits in a single chip. The best spectral sensitivity

is used to closely capture real human eye responses.

VEML3235 has excellent 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 less than 1 μA.

VEML3235’s operating voltage ranges from 2.6 V to 3.6 V.

VEML3235 can detect a wide range of ambient light power.
