Please take a look at the OSPi user manual:

page 5 — Rain Sensor.do you mean that I connect the rain sensor to the GPIO 14 + gnd on my raspberry PI3 it could work?
if it were so I would be so happy!

No, he is talking about connecting it to the rain sensor port on the OSPi board (far right connector next to stations). That connector is connected (internally) to the GPIO 14 that you show on your picture.
Does not matter which RPi you have: they all have the same pin definitions so yes it works for RPi 3 too.
Sorry sir only another question,
it is possible connect all type of rain sensor?
for example this:
https://www.amazon.com/Hunter-Industries-MINICLIK-Mini-Click-Sensor/dp/B001400LTU
or this:
https://www.amazon.com/Orbit-Sprinkler-System-Freeze-Sensor/dp/B000A7SPPU
Yes I think both of them would work with OpenSprinkler / OpenSprinkler Pi. Most rain sensors are simply rain-activated switch — some are normally open (i.e. switch is disconnected when there is no rain) but most common ones are normally closed (i.e. switch is on when there is no rain). OpenSprinkler software allows you to choose between the two types of sensors.
hello, I try to enable rain senso without connection the sensor.
if normal open it is checked or not I have in both case rain detect message, why??I use the Hunter Industries sensor – you may need to adjust the polarity inside the config for it to work correctly but once that is done it just works.
Is it also possible to connect the rain sensor direct on GPIO 14? Is a Pull-UP or Pull-Down required? I didn´t found documents for this.
