VEML6035 Digital Light Sensor operates via simple I²C


Vishay’s low-power, high-sensitivity, ambient light sensor operates via simple I²C command

Vishay’s 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, thereby eliminating loading on the host. The active average power consumption is approximately 300 μW.

VEML6035 incorporates a photodiode, amplifiers, and analog/digital circuits in a single chip. Vishay’s patented Filtron™ 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 temperatures and its refresh rate setting does not need an external RC low-pass filter. There is a programmable shutdown mode which reduces current consumption.
