GY-1145 DC 3V I2C Calibrated SI1145 Flora UV Index IR Visible Light Digital Sensor Module. The SI1145 is a new sensor from SiLabs with a pre-calibrated UV sensing element that can calculate UV Index. This has been kept outside a couple days and compared the calculated UV index with the news-reported index and found it was very accurate! The sensor also has visible and IR sensing elements so you can measure just about any kind of light. However the precision measurements are for the UV light as it has been pre-calibrated for UV light . Though you can also get a fairly good idea of the lux measurement of ambient light with this sensor. However for accurate measurement of ambient light please check out the other sensors like MCU-3301 OPT3001 available on the website.
