Vishay Semiconductors VEML6030 ambient light sensor

The Vishay Semiconductors VEML6030 digital ambient light sensor combines a sensitive photodiode, a low-noise amplifier and a 16-bit ADC in a miniature, transparent surface-mount package measuring 2 x 2 x 0.85 mm. The sensor adopts Filtron technology and features an interrupt function while supporting an I²C bus interface for simple operation.

Operating over a temperature range of -25 to +85°C, the device provides display and keypad dimming adjustment and optical switching for mobile devices such as smartphones and GPS units; notebooks and PC computers; LCD TVs, digital picture frames and digital cameras; and industrial and medical light sensing. As part of smart home lighting control systems, the product provides analysis of ambient lighting to give precise control even during unexpected situations, such as fast-moving storms. The device detects fading natural light and can detect the sun rising in the morning to control light levels.

Filtron technology enables ambient light spectral sensitivity close to that of the human eye, while the sensor’s adoption of O-Trim technology provides output tolerance of ≤10%. The device offers detection from 0 lx to 167 klx and resolution down to 0.005 lx/ct, allowing for operation in applications with low-transmittance (dark) lens designs.

The sensor provides 100 Hz and 120 Hz flicker noise rejection and good temperature compensation stability. It features low power consumption down to 2 μA in operating mode and 0.5 μA in shutdown mode.
