Here you can download the software for my Arduino Nano based Sky Quality meter (SQM) using the TSL2591 Light Sensor Module from AdaFruit, to be featured in my upcoming book, Practical Projects for Astronomers.

The software overcomes the low light resolution limitations of the TSL2591 by using oversampling, allowing it to give useful results at very dark sites.

The zip folder also includes STL files for 3D printing parts to go with a 50 x 60 x 120 enclosure.
