The Vishay VEML6070 UV light sensor shipped by Mouser Electronics

Mouser Electronics is now stocking the VEML6070 UV Light Sensor from Vishay Intertechnology. The VEML6070 is an advanced, CMOS ultraviolet (UV) light sensor with an I2C protocol interface and high dynamic detection resolution. With an integrated signal conditioning IC, photodiode, amplifiers, and analog/digital circuits in a single chip, the VEML6070 provides excellent measurement in a small 2.35 x 1.8 x 1.0mm package, which makes it ideal for applications such as handheld devices, wearables, and health and fitness devices.

The Vishay VEML6070 UV Light Sensor, available from Mouser Electronics, contains an 8-bit command register written via the I2C bus. All operations can be controlled by the command register, with a simple command structure that enables engineers to easily program the operation setting and latch the light data from the sensor. The sensor offers 16-bit resolution to convert solar UV light intensity to digital data, and includes an active acknowledge feature that allows it to transmit ultraviolet index (UVI) alerts based on programmable thresholds.

The VEML6070 sensor operates on a supply voltage of 2.7V to 5.5V with typical current ratings of 250 µA (supply) and 1 µA (standby). The sensor detects the entire spectrum of UVA and UVB wavelengths (280–400 nm), with a typical sensitivity of 5 µW/cm2/step and a maximum detection of 328 mW/cm2. The device is compliant to RoHS directive 2002/95/EC, is free of halogens, and is compatible with lead-free (Pb-free) soldering. The VEML6070 is ideal for a variety of mobile, lighting, and sensor applications, including smartphones, digital cameras, industrial devices and displays.
