Hello,
I have found this weather station that outputs the data to RJ-11. How can I communicate it with Arduino MEGA 2560, without using a shield. Is there any other solution?
Thank you
The datasheet link in the page you linked to describes the pins of the RJ11 connector for the rain gauge and the windspeed device but not the wind direction device - perhaps it uses the remaining pins.
I think there is enough info in the datasheet to write an Arduino program to interpret the data.

The problem is that I have never before interfaced RJ-11 protocol with Arduino. I am searching it though... and I also thought of asking here, if any experienced person could help.
Thank you
Also, how do I measure evapotranspiration? So that I can sense the tree, and send the measurements to the Arduino?

RJ11 is a connector, not a protocol.
The datasheet describes the format of the data.
Simplest thing might be to cut the RJ11 off and just solder the wires to a piece of PCB with header pins that can connect into the Arduino sockets. Be sure to identify all the wires before you cut anything - make a clear drawing for yourself, and don't lose it.
I believe you will need one Arduino analog input so you cold connect everything to the analog pins because they also work as digital pins.
