The Telescope Encoder and Sky Sensor (TESS-W) is the first model of TESS photometers, compact devices to monitor sky brightness every night developed under Stars4All project.
TESS-W photometer sending data today
Designed by astronomers and calibrated on LICA laboratory at Universidad Complutense de Madrid the quality of the data is scientifically accurate.
“Absolute Radiometric Calibration of TESS-W and SQM Night Sky Brightness Sensors” Bará, Tapia & Zamorano (2019)
TESS photometer is mounted on a weatherproof enclosure (83x60x32 mm). Wherever there is electricity and WIFI you can install it and get the measures online trough the remote observatory.
Its temperature and IR sensor will let you know whether the sky is clear or cloudy.
