A new UV sensor has been added to the weather station. It measures the current UV radiation as an UV index number, thus providing an indication on the danger level related to the sunlight. The present measurement is now shown on the weather page. Some useful information on the UV index:
Its purpose is to help people to effectively protect themselves from UV light, of which excessive exposure causes sunburns, eye damage such as cataracts, skin aging, and skin cancer (see the section health effects of ultraviolet light). Public-health organizations recommend that people protect themselves (for example, by applying sunscreen to the skin and wearing a hat) when the UV index is 3 or higher.
