UVIS25 - Digital UV Index sensor

General Description

The UVIS25 is a digital UV Index sensor able to provide an accurate measurement of the Ultraviolet radiation index (UVI) from the sunlight.

It includes a sensing element and a mixed signal ASIC to provide the UV Index data trough I2C and SPI interfaces.

Key Features

  • 0 - 15 UV Index output range.
  • Resolution: UVI/16.
  • Active and power down modes.
  • Continuous reading at 1 Hz ODR / one shot mode.
  • Interrupt functions: Data Ready and UVI thresholds.
  • SPI and I²C interfaces.
  • Supply voltage: 1.7 to 3.6 V.
