The SI1145 is a new sensor from SiLabs with a calibrated UV sensing element that can calculate UV Index.\u003c\/span\u003e\u003cspan style=\"font-size:14px;\"\u003e2. We took this outside a couple days and compared the calculated UV index with the news-reported index and found it was very accurate!\u003c\/span\u003e\u003cspan style=\"font-size:14px;\"\u003e3. It's a digital sensor that works over I2C so just about any microcontroller can use it. \u003c\/span\u003e\u003cspan style=\"font-size:14px;\"\u003e4. The sensor also has visible and IR sensing elements so you can measure just about any kind of light - but only the UV sensor has a calibrated output so if you need precision Lux measurement check out the TSL2561.\u003c\/span\u003e\u003cspan style=\"font-size:14px;\"\u003e5. If you're feeling really advanced, you can connect up an IR LED to the LED pin and use the basic proximity sensor capability as well.\u003c\/span\u003e\n\u003c\/div\u003e\u003cdiv\u003e\u003cdiv\u003e\n\u003cstrong\u003e\u003cspan style=\"font-size:16px;\"\u003eSI1145 details:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan style=\"font-size:14px;\"\u003e1.
