FreeDSM is a device that allows you to measure the quality of the sky background during your night observations. It is a photometric instrument that incorporates the Osram TSL2591 sensor, with two diodes: one will make a measurement in the infrared range and the other full spectrum. From those measurements, it provides the measurements in mpsas (its range is 12-23 mpsas).

It is a photometric instrument that incorporates the Osram TSL2591 sensor, with two diodes: one will make a measurement in the infrared range and the other in the full spectrum. From those diods, it provides the mpsas measurements every minute (its range is 12-23 mpsas).

You can build your own FreeDSM with the information contained here, by assembling very cheap and easily available components and some small parts for the chassis that you can print on any 3D printer. It withstands the elements without difficulties, it is small and incorporates a battery, which will allow you to use it portablely, although you can also install it permanently, even ignoring the installation of the battery inside and its charge regulator. The software is based on [Tasmota](https://tasmota.github.io/), making it easy to integrate data across a multitude of environments and to include hundreds of additional sensors. The license of the firmware is GPL3.0 and additional proccesing in Berry code run by FreeDSM.
