The UVIS25 is a digital UV index sensor able to provide an accurate measurement of the ultraviolet radiation index (UVI) from sunlight. It includes a sensing element and a mixed signal ASIC to provide the UV index data through I2C and SPI interfaces.
A dedicated technology has been developed to achieve the greatest accuracy for UV index measurements.
The UVIS25 allows the measurement of the UV index, without the need for a dedicated algorithm to calculate the UV index and without specific calibrations at the customer manufacturing line.
The device can be configured to generate interrupt events based on a threshold crossing or when a new set of data is generated. The event is available in a register as well as on a dedicated pin.
The UVIS25 is available in a full-mold LGA package (LGA). It is guaranteed to operate over a temperature range extending from -20 °C to +85 °C. The package is transparent to allow external solar radiation to reach the sensing element.
