Dubbed the first sensor to provide a direct digital output of the Ultraviolet Index (UVI), the UVIS25 digital UV sensor targets all UV-sensing markets, including wearable devices, smartphone and tablet apps, and IoT apps. The device is sensitive to UV waves in the 200 nm to 400 nm range, encompassing the key UV-A (315 nm to 400 nm) and UV-B (280 nm to 315 nm) wavelengths that are of greatest concern to human-health effects. Above sensing, the UVIS25 calculates the UVI internally, eliminating the need for external processing algorithms or calibration on the customer’s manufacturing line. Other features include a UVI output range of 0-15 with a resolution of1/16, SPI and I2C interfaces, 1.7 to 3.6 V supply voltage range, and the ability to provide updated UVI values as often as every second. The device is supplied in a 2.5 mm x 2.5 mm x 0.76 mm LGA-10L transparent molded package. Pricing is $1.70 each/1,000.
