As one of the first mission I am planning to create is a sense-it mission that measures the sunlight in different countries of Europe, the light sensors in various devices should be checked and scaled if needed. For this purpose, I created a mission that compares light sensors from different devices. The mission can be found here.
For the measurements I used a Halogen 42W light bulb of 630 Lumen, I placed the devices flat 1 metre away from the light and uploaded 3 series from each device. The measurements for all the devices were taken consecutively, using the same light source, ambient light and distance from the light. An expert is currently helping me to analyse the data.
