Can I leave the AirBeam2 outside to measure PM in one location over time?

You can use the AirBeam2 and phone to measure air quality in one location over time as long as it is protected from direct sun, rain, and extreme weather. Keep in mind that the paired phone will need to be next to the AirBeam2 during data collection. If you plan on leaving the phone and AirBeam2 on for multiple hours, it is recommended that you plug them in if possible.

Note that due to the limited accuracy of the mobile device's GPS, this single measurement location may appear on the map as a series of locations near the actual sampling location.
