Vishay Semiconductors VEML High Accuracy Ambient Light Sensors

Vishay Semiconductors VEML High Accuracy Ambient Light Sensors are housed in miniature transparent packages and feature an easy-to-use I²C interface. These digital 16-bit resolution sensors include a high-sensitive photodiode, low-noise amplifier, and a 16-bit A/D converter. The VEML series has an operating voltage of 2.5V to 3.6V with an I²C BUS voltage range of 1.7V to 3.6V. Vishay Semiconductors VEML High Accuracy Ambient Light Sensors provide additional ambient light functions such as temperature compensation and high dynamic detection resolution with a software shutdown mode control.

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.
