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.
A dedicated technology has been developed to
achieve the best accuracy for UV Index
measurements.
The UVIS25 allows the measurement of the UV
Index, without the need of a dedicated algorithm
to calculate the UV Index and without specific
calibrations at 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 in 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.
Applications
• UV Index measurements
• Wearable devices
• Smartphone and tablet
• Weather stations
