Ultraviolet radiation, a possible cause of skin cancer, is strengthening each year owing to global warming. UV-MONI has been developed and designed as a portable ultraviolet monitor to help people monitor their exposure to these harmful rays when venturing outdoors. Resembling a colorful stopwatch, users can measure the strength of ultraviolet radiation emitted by simply pointing the device at the sun and pressing the button. The UV-MONI uses an international standard index, and data are displayed using one of five code colors – allowing for an intuitive understanding of ultraviolet measurements. One of the aims behind product development and design was to encourage a more visual approach to observing our everyday environment, and to increase awareness of environmental issues.
