The sensor MS V3.1 used here is a prototype and tests made with it were taken in many different locations.
It has two embedded sensors. One sensor (TSL 2561) measure the illuminance level using two photo-diode. The other (ISL 29125) one has three different kind of photo-diodes, each sensible to specific part of the spectrum, which give information on the red, green and blue proportion of the light composition.
All values from those described sensors are gathered by an ESP32 (Huzzah Feather version by Adafruit). Then, the ESP send all those values to one database of this website for them to be finally displayed on this webpage.
This page exposes values gathered in indoor environments by the sensor MS V3-1. You will find the lux level as other more details informations about the light composition of the studied enviroments.
Please note that those measurements are made in the context of my Ph.D thesis and are consequently not free of use. I reserve the right to give access to these data as well as to make them inaccessible if I deem it necessary. Thank you for your understanding.
