Vishay Semiconductors VEML6075 integrated UVA and UVB light sensor

The Vishay Semiconductors VEML6075 is an integrated ultraviolet (UV) light sensor for the detection of UVA and UVB light intensity.

Featuring Filtron technology for high UV sensitivity and linearity, the product incorporates an IC with five sensitive areas and signal processing in a 2 x 1.25 x 1 mm surface-mount package while offering an I²C bus interface for simple operation. It saves space and increases design flexibility by incorporating the circuitry needed for consumer, medical and industrial applications in one compact unit.

The sensor offers individual UVA and UVB channels with 16-bit resolution and good sensitivity of 365 and 330 nm, respectively. Designed to convert solar UV light intensity to digital data, it provides a measurement of signal strength and allows for true UVI calculation in smartphones, smart watches, sport bands, notebook computers and weather stations. The UVI value indicates how much UV radiation will reach human skin when outside, allowing precautions to be taken to avoid sunburns in the short term and skin cancer in the long term.

The device delivers high performance under long-term solar UV exposure and offers high temperature compensation stability from -40 to +85°C. It features a shutdown mode that reduces power consumption to 800 nA and an operating voltage range of 1.7 to 3.6 V, making it suitable for portable electronics and wearable devices.
