"It’s beautiful here in Boulder, Colorado, but any newcomer to the area quickly discovers our wonderful 300 days of sunshine is tempered with the fact that Boulder is located at 5,430 ft (1655m) above sea level. You can get a sunburn incredibly fast here! The ZOPT2201 is an excellent UVBS (ultraviolet energy sensor) in that it does true 310nm UVB sensing, not interpolated UV from ambient light like most sensors on the market. Without fuss or weird look up tables this sensor gives the...
