Rural farm: wireless dish and router is in old farm house (user, password active). Antenna that connects to network is in new house (wireless, password active). Sensor lights active. I have done all troubleshooting suggested and do not have Sensor wifi access to Purple Air to be able to set it up. Aspen Springs Rustic Barn, Lacombe County.

> What PurpleAir Sensors Measure Measurements taken by PurpleAir sensors include: Particulate matter VOCs\* Temperature Pressure Relative humidity These and other derived data can be viewed on the [PurpleAir Map](https://map.purpleair.com/) by opening [map settings](https://community.purpleair.com/t/purpleair-map-guide/90#p-117-configuration-menu-7) and selecting the appropriate data layer.
