3.6.2. Data file
The ObservAir data is written in comma separated value (csv) format to a
.txt file. Each line in the file represents a datalogging event, and starts with
the character “$”. Values are listed in the order provided in the colNames
field of the corresponding setting entry. Typical data output from a base
model ObservAir measuring only black carbon is shown below. If other
sensors are fitted to the unit, such as gases or PM, the output data will be
appended to each line in the order listed in the colNames field.

3.7. Cloud Dashboard Interface (WiFi or LTE)
ObservAir Cloud Dashboard is the recommended interface for interacting
with the ObservAir. It enables networked interfacing with ObservAir
instruments via smartphone app (iOS/Android) and web browsers. The
dashboard can be used to remotely monitor and download data, adjust
instrument settings, and facilitate easy deployment of sensor networks.
