Recently, Vishay Intertechnology, Inc. announced the launch of the new integrated UV sensor, the VEML6070, which uses Filtron UV technology for high UV sensitivity and linearity. The Vishay Semiconductors VEML6070 integrates an optical pin diode and signal processing IC into a small 2.35mm x 1.8mm x 1.0mm surface mount package that converts solar UV light into consumer, medical, and industrial electronics applications. Digitized data, providing an I2C bus interface to simplify operation.

Vishay introduces new integrated UV sensor

Today's devices are suitable for UV detection in smartphones, health monitoring and fitness products, flame detectors and weather stations. The sensor combines the circuitry required for these applications in a small unit with a robust refresh rate setting, eliminating the need for an external RC low-pass filter, reducing cost and simplifying design.

The high dynamic detection resolution maintains excellent performance with long-term exposure to solar ultraviolet light. The active response (ACK) with threshold window setting emits a UVI warning signal under intense daylight conditions.

VEML6070 has a built-in optical pin diode with a spectral sensitivity of 280 nm to 400 nm and a peak sensitivity wavelength of 355 nm. The sensor is not affected by the strobe of the fluorescent lamp. The software shutdown mode reduces the power consumption to less than 1μA and has good temperature compensation stability in the range of -40°C to +85°C. The device's operating voltage and I2C bus voltage range from 2.7V to 5.5V in a lead-free OPLGA package. VEML6070 is RoHS and Vishay green and halogen free.

New UV sensors are available now and are in volume production, with lead times of six to eight weeks for larger orders.
