Project description
UV-watch is a fully open watch project featuring an calibrated
UV-light sensor. It will give an alarm when it detects dangerous levels
of UV light and is meant for people with a highly sensitive skin.**
The full design (electronics, mechanics and software) is available under
free licenses and the design is exclusively made with free tools.
The project started when the need came up during ThePort hackathon 2015.
