Outdoor Arduino projects, especially temperature, humidity, and barometric pressure, need access to outdoor environmental conditions, but protection from sunlight and rain. This is done with a louvered box called a Stevenson Screen or Cotton Region Shelter.
“A Stevenson screen or instrument shelter is an enclosure to shield meteorological instruments against precipitation and direct heat radiation from outside sources, while still allowing air to circulate freely around them. It forms part of a standard weather station. The Stevenson screen holds instruments that may include thermometers (ordinary, maximum/minimum), a hygrometer, a psychrometer, a dew-cell, a barometer and a thermograph. Stevenson screens may also be known as a cotton region shelter, an instrument shelter, a thermometer shelter, a thermoscreen or a thermometer screen. Its purpose is to provide a standardised environment …” – http://en.wikipedia.org/wiki/Stevenson_screen
