Vishay Semiconductors VEML高精度環境光感應器

Vishay Semiconductors VEML高精度環境光感應器具有易於使用的I²C介面，並採用微型透明封裝底座。此數碼16位元解決方案感應器包含高靈敏度光敏二極管、低雜訊放大器和16位元A/D轉換器。VEML擁有2.5-3.6V操作電壓，I²C BUS電壓範圍為1.7-3.6V。這些感應器備有額外環境光功能，例如具有軟件當機模式控制的卓越溫度補償和高動態偵測。

The VEML6030 sensors offer a cost-effective alternative to a lux meter. Under all lighting conditions, the VEML6030 output is within 10% of a calibrated lux meter. The VEML6030 devices incorporate photodiodes, amplifiers, analog/digital circuits, and an I²C interface in a single-chip. The sensors feature Filtron™ technology, Vishay's on-chip optical filtering.
