Project description
LUVI is a handheld Low UV Intensity meter meant for people with a highly sensitive skin to check if they are in a UV-free environment. The meter is developed in collaboration with the French Enfants de la Lune association.
The full design (electronics and mechanics) is available under free licenses and the design is exclusively made with free design tools.
The project started with ThePort hackathon 2015 to help children suffering from Xeroderma pigmentosum (XP), a genetic disorder that causes extreme sensitivity to ultraviolet light.
