My old UV sensor has probably saved my life on a number of occassions. It has certainly stopped many arguements about the extent to which it is a good idea for me to go outside. Some members of my family are still trying to use their eyes to measure UV.
Now it has died and I need to get another. There are many more choices than were available a few years ago. Do you guys have any recommendations?
