Using the brightness sensor on the most modern smartphones returns the expressed value in both lux (lx) and foot-candle (fc).
You can change the unit of measurement from lux (lx) to foot-candle (fc).
If you want to have detailed information about the units of measurement there is a key that directly refers, and in the language set, to the Wikipedia page inherent to the units of measurement on the brightness.
There may be a small difference in values between one smartphone and the other as the sensors are not all the same. For example, in the settings pane, among other things, you can calibrate the value shown with respect to the smartphone sensor.
The table that shows the values of watts equivalent to the illumination value shown is the result of in-depth studies in this area.
In this regard, extensive documentation is available on the Internet.
To measure the value of environmen- tal brightness as accurate as possible you should have some notions about it, one on all is the distance you have to keep from a light source and smartphone.
Extensive documentation is available on the Internet.
The languages you can set are five: English, Italian, French, Spanish, and German.
Permissions:
Accessing the internal memory of the smartphone to record the set data (language, unit of measurement, value calibration etc etc);
Internet access.
