“STARS4ALL night sky brightness photometer”
TESS-W is the first version of a series of inexpensive but reliable photometers that are used to measure night sky brightness. This photometer has been designed based on Cristobal García photometer TESS.
- Itis mounted on a weatherproof enclosure (83x60x32 mm) and sends automatically the brightness values to a data repository using a WIFI to connect the Internet so can be used as a fixed station toconstantly monitor the sky brightness at night.
- The device includes an infrared sensor to estimate the cloud coverage.
- It has been calibrated at LICA laboratory the quality of the data is scientifically accurate.
- The band pass is extended to the red with respect of that of the Sky Quality Meter (SQM).
- The photometer could also be used in local mode connected to a computer or tablet to gather data from a moving vehicle.
- The photometer was developed within STARS4ALL project, a collective awareness platform for promoting dark skies in Europe, funded by the EU.
Hundreds of units have already been deployed around the world. The photometers on the TESS network share their measurements in an open data repository.
