With all the focus on skin cancer caused by too much exposure to sunlight, you might expect a UV-measurement gadget to be designed to warn you when you’ve spent too long in the sun. But no, the SunSprite has the opposite goal: it’s aimed at those who spend all their time indoors, and don’t get enough time in the sun. Or, to put it more concisely, geeks.
Sunlight plays a role in both mood and sleep patterns. The SunSprite measures exposure to both visible and UV light, and uses LEDs to indicate when you’ve met your daily goal of having spent enough time outside. It also communicates with a companion iPhone app. The retail price is a rather hefty $149, but early bird Indiegogo backers can get one for $89.
A neat thing about it is the same sunlight it measures also powers the device. The low energy requirements of the SunSprite mean that just a few minutes of sunlight provide enough energy to power the gadget for a week.
