• SI1145 Digital UV Index / IR / Visible Light Sensor

Description:
The SI1145 is a new sensor from SiLabs with a calibrated UV sensing algorithm that can calculate UV Index. We took this outside 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 - we only wrote our library to printout the 'counts' rather than the calculate the exact values of IR and Visible light so if you need precision Lux measurement check out our other light sensors (see related products). 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.
