I am new to Arduino and Raspberry Pi, and I have no eletronics knowledge outside of this. I have a good programming background.
I just learned how to solder (basic), got my LCD working, my rain sensor, external temperature sensor, barometric sensor and camera working. They are connected and logging data.
Now I want to put this thing outside. I'll need long wires for my rain sensor and temperature sensor. Can I dismantle a network cable (Furukawa Cat 6) and use the pairs inside?
I'll need two wires for the rain sensor and three for the temperature sensor. One network cable has more than enough pairs, so I'll just need to pass one cable.
I plan to dismantle both ends and solder.
Is this okay? What is the maximum distance?
The distance would be about 20 meters.
The protocols and interface - I don't know, but I'll look into the datasheets. The barometric pressure sensor is Bmp180, the temperature sensor is the DS18B20(the datesheet of ds18b20
and the rain sensor is the YL-83.
