It took me a little to understand what this gadget is about and when I understood it, it seemed very interesting because it helps us to have a clearer and more professional idea of the amount of sunlight we are exposed to. Basically, we can have very detailed information about the amount of sun rays that our body absorbs as well as the intensity of them. With this small gadget we can monitor and know when we definitely need to go outdoors, and for obvious reasons, this gadget is powered by solar energy.

Well done.
