Sunshine duration calculation with CSD3

In weather stations with CSD3, sunshine duration is calculated as follows:

1. The weather station polls the sensor 6 times in a minute and saves these samples.

2. Every minute, the 6 last samples are evaluated and compared to a predefined limit value (default = 4):

   • If as many or more samples than the limit value indicate sunshine, the minute is counted to sunshine duration.
   • If less samples than the limit indicate sunshine, the minute is not counted to sunshine duration.
