Vishay : Ambient light sensor VEML6030X01 for automotive applications offers accurate digital output


VEML6030X01: highly sensitive to changes in ambient light intensity

The optoelectronics group of Vishay Intertechnology has extended its family of integrated ambient light sensors with the release of the VEML6030X01 for use in automotive applications.

The VEML6030X01 incorporates a photodiode and signal processing IC in a compact, six-pin 2mm x 2mm x 0.85mm surface-mount package. It captures measurements of the intensity of ambient light over a range from 0.005 lux to 167 klux, providing them as a digital output over an I2C bus interface to any microcontroller. Its high 16-bit resolution, enabling the VEML6030X01 to detect changes in ambient light of as little as 0.005 lux, enables it to be used reliably behind dark, inked glass.

The new sensor features an on-chip optical coating which modifies the photodiode’s normal response in such a way as to match the response of the human eye to ambient light. The device’s measurements of ambient light are accurate to a maximum of ±10%.

The sensor’s output is very stable over a temperature range of -40°C to 110°C.
