Although TESS-W is designed to create a monitoring station and to join the STARS4ALL network it is possible to read and store data locally for remote places with no Internet connection such deserts or natural parks.
To do so, you will need same tess.apk software used for TESS-P (see above information) and the smartphone to connect to your TESS-W photometer via WiFi.
TESS-W could be also used as TESS-P on a moving vehicle to map the sky brightness of a region.
TASS photometer works with the same app as TESS-P
The 140 data point all along the celestial vault are recorded and they are used to create a map.
The all-sky night sky brighness map is similar to those of the NixNox Project.
