Vishay announced a new high-precision, digital ambient light sensor for consumer products and industrial applications. Of the "VEML6030"United in a 2 2 x x 0,85 mm tiny, transparent SMD package highly sensitive photodiode, a low noise amplifier and a 16-bit A / D converter. The sensor uses the Filtron technology, provides an interrupt function and has an I²C bus interface for easy communication with the host controller.
Specified for the operating temperature range of -25 ° to + 85 ° C, the sensor is designed for dimming displays and keyboard backlights and for use as an optical switch. Typical end products include mobile devices such as smartphones and sat navs, notebooks and personal computers, LCD televisions, digital photo frames and digital cameras, industrial systems and medical devices. As part of a smart home lighting control system, the VEML6030 provides real-time, accurate ambient light analysis that enables it to respond to fast-changing lighting conditions like a storm. It detects increasing dusk and morning sunrise and allows for automatic adaptation of the artificial light.
Thanks to the Filtron technology, the sensor has a similar spectral sensitivity as the human eye. The O-Trim technology provides a tight output tolerance of ≤ 10%. The sensor has a detection range from 0 lx to 167 klx and a high resolution of 0,005 lx / ct. This makes it suitable for applications with a dark tinted window.
