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.
