This little (aluminum!) weather station would look pretty deluxe in an Airstream:
Takes air quality measurements to monitor and track your environment. A great app for both in and outdoors, it wirelessly transmits data such as temperature, barometric pressure, humidity, and CO2 concentration to your device from a range of 100m. Data is readily available through your personal Netatmo account and can be shared with family and friends. Stay one step ahead, come rain or shine.
For iPhone and Android | $179. More info on the Netatmo website here.
