SI1133 UV Index/Ambient Light Sensor IC

3. Functional Description The Si1133 is a UV and Ambient Light sensor whose operational state is controlled through registers accessible through the I2C interface. The host can command the Si1133 to initiate on-demand UV or Ambient Light measurement. The host can also place the Si1133 in an autonomo.

Si1133 Data Sheet UV Index/Ambient Light Sensor IC with I2C Interface The Si1133 is a UV Index Sensor and Ambient Light Sensor with I2C digital interface and programmable-event interrupt output. This sensor IC includes dual 23-bit analog-to-digital converters, integrated high-sensitivity array of UV, visible and infrared photodiodes, and digital signal processor. The Si1133 is provided in a 10-lead 2x2 mm DFN package and capable of operation from 1.62 to 3.6 V over the 40 to +85 °C tem.
