AvE over on the YouTubes shared a vidjah on how he used an Adafruit SI1145 UV sensor to test the effectiveness of those cheap knock-off branded sunglasses. Do they actually shield your eyes from from UV light or will they leave you chooched?
I wear cheap sunglasses. Do they filter UV or are they slowly cooking my baby blues?

Sorry, the comment form is closed at this time.
SI1145 is not a UV sensor. It is a visible/IR sensor which correlates sunlight intensity and visible/IR ratio to a UV index. It is only accurate for outdoor sunlight situations. My guess is you could make it show a high UV index with a green LED, as there would be no IR component.
You should use http://www.adafruit.com/products/1918 for actual UV measurements.
