Vishay — VEML6031X00 Digital Ambient Light Sensor

The VEML6031X00 from Vishay is a digital ambient light sensor in a miniature package which enables the accurate control of light output in automotive applications such as display backlighting. Typical measurement tolerance is a maximum 10% under various light sources.

Housed in an opaque surface-mount 2.67 mm x 2.45 mm package, the VEML6031X00 includes a highly sensitive photodiode, a low-noise amplifier, and a 16-bit ADC. The VEML6031X00 ambient light measurements are supplied as 16-bit digital values via an I2C interface.

High resolution and a wide dynamic range mean that the sensor can detect light at levels from 0 lux to 228 klux, and is suitable for use underneath a dark lens or cover glass.

The sensor features Filtron™ wafer-level optical filter technology which makes the VEML6031X00 spectral sensitivity to ambient light very similar to that of the human eye.
