VEML6035傳感器變送器的光學(xué)傳感器-環(huán)境光IR紅外線UV紫外線傳感器規(guī)格書PDF中文資料

DESCRIPTION

VEML6035 is a 16-bit low power, high sensitivity CMOS

ambient light sensor operated via a simple I2C command.

The sensor offers an active interruption feature that is

triggered outside of the threshold window settings

eliminating loading on the host. Active average power

consumption is around 300 μW.

VEML6035 incorporates a photodiode, amplifiers, and

analog / digital circuits in a single chip. Vishay’s patented

FiltronTM technology, a wafer level optical filter, provides

the best spectral sensitivity to match human eye responses.

The sensor has excellent temperature compensation to

maintain output stability under changing temperature and its

refresh rate setting does not need an external RC low pass

filter. There is a programmable shutdown mode which

reduces current consumption to 0.5 μA. Operating voltage

ranges from 1.7 V to 3.6 V.
