SI1145 Digital LUX/UV & IR Sensor Module

The SI1145 is a new sensor from SiLabs with a calibrated light sensing algorithm that can calculate UV Index. It doesn't contain an actual UV sensing element, instead it approximates it based on visible & IR light from the sun. The module has been tested outside for a couple days and compared the calculated UV index with the news-reported index and found it was very accurate. It's a digital sensor that works over I2C so just about any microcontroller can use it. The sensor also has individual visible and IR sensing elements so you can measure just about any kind of light - the library was written to only printout the 'counts' rather than to calculate the exact values of IR and Visible light. If you're feeling really advanced, you can connect up an IR LED to the LED pin and use the basic proximity sensor capability that is in the SI1145 as well.
