Viewing and Acquiring Data with the AQSync
A.1.2.1
Viewing AQSync Data via the Touchscreen
Real-time data can be viewed using the touchscreen of the AQSync. Individual screens
show the data for each of the AQSync measured quantities (ozone, NO
2
, etc.). In
addition, a graphing function allows viewing of the continuous data stream for any of the
measured species.
The screen functions are intuitive but are more fully explained later in this manual.
A.1.2.2
Accessing AQSync Data via the Web and via USB
As shipped from the factory, the AQSync is configured so that data from its instruments
and sensors are integrated and then transmitted via cellular or WiFi to the web every 5
minutes.
This integrated web-based data stream is the primary data acquisition mode
for use of the AQSync.
The upload frequency of the measurements is set at a default value of 5 minutes at the
factory. However, if desired this setting can be changed by the user in
the instrument’s
touchscreen menu. Shorter times are not generally recommended because of
prohibitive cellular costs.
Each data line contains the chemistry

meteorological measurements made by

(temperature,

humidity, wind), location, time, and
status of the
sensor package’s battery.
The data can be exported to a computer
for subsequent analysis.
Data files for each measured species are
also stored internally for USB access.
At the factory setting of 5 minutes (or the
user’s chosen frequency), the AQSync
uploads the measurements and transmits
them to the web.
User accesses data on the web. Data may also
be viewed in real time on the AQSync
touchscreen, and data files for each measured
species can be downloaded via USB stick.
