Single customizable logaritmic formula version. When the screen turns on/off the flow adjusts the screen brightness automatically according to the amount of ambient light.
This version calculates the brighness using a single, easily customizable formula.
To customize the equation, change the parameters in the first three blocks:
MinBright: minimum brightness
MaxBright: brightness at max ambient light*
Gain: change transition**
* Maximum ambient light is 30.000lux.
Default MaxBright : 40%. Set to a higher value if you prefer a bright Screen!
** Higher Gain means brightness will change faster for low lighting. Lower Gain means more light needed for change, but more severe changes at higher lighting cases. Default Gain: 0.1, normal range: [0.1, 3.0]
***Note that the default settings result in an overal fairly dark screen. If you prefer a brighter screen it is best to start with finding a suitable MaxBright setting during daytime or high lighting situations. And afterwards finetuning with the Gain parameter.
The formula is based on a logarithmic scale of the light intensity, and is defined as:
Brightness = MinBright + gain * log10(lux) ^ power
power is calcutated by solving:
MaxBright = MinBright + gain * log10(3e5) ^ power
Block count: 21
